Variant 1 easy answer: June = 200 books, July = 300 books

The line graph shows the books sold recorded each month. In June the count was $40$ more than in May, and the number in June and July together is $500$ . Complete the line graph.

(Figure) A line graph titled "Books Sold." The horizontal axis shows the month - $3$ (March), $4$ (April), $5$ (May), $6$ (June), $7$ (July). The vertical axis shows the number of books, with major gridlines at $0$ , $100$ , $200$ , $300$ , $400$ and each small grid square worth $20$ books. Points are plotted and joined for March at $120$ ; April at $220$ ; May at $160$ ; the points for June and July have not yet been plotted.

1 · Understandwhat's really being asked

A line graph of books sold each month shows March = 120, April = 220, May = 160; June and July are blank. June is 40 more than May, and June + July together is 500. I must find the June and July counts to complete the graph.

Givens

March = 120 books, April = 220 books, May = 160 books
June = May + 40
June + July = 500
Each small grid square = 20 books

Unknowns

1Find June

#7 Identify Subproblems 4.OA.A.3

June is 40 more than May, and May is 160, so June = 160 + 40 = 200.

160 + 40 = 200

Start from the value you already know and apply the given step.

2Find July

#11 Work Backwards 4.OA.A.3

June and July together make 500, so July = 500 - June = 500 - 200 = 300.

500 - 200 = 300

Knowing the total and one part, subtract to recover the other part.

On the graph (each square = 20), June 200 sits 0 squares above 200, and July 300 sits 0 squares above 300; join the points with straight segments.

200 = 200 + 0\times 20,\quad 300 = 300 + 0\times 20

Converting the numbers into squares lets you place each point exactly.

Answer: June = 200 books, July = 300 books

4 · Reviewdoes it hold up?

Check the clues: June 200 is indeed 40 more than May 160, and June 200 + July 300 = 500 as required. Both values land neatly on grid lines (multiples of 20), so the plotted points are valid.

Another way: Convert to algebra (tool 13): let June = J = 160 + 40 and July = 500 - J; solving gives the same J = 200 and July = 300.

1 · Understandwhat's really being asked

A line graph of toy cars made each week shows Week 1 = 200, Week 2 = 300, Week 3 = 240; Week 4 and Week 5 are blank. Week 4 is 60 more than Week 3, and Week 4 + Week 5 together is 700. I must find the Week 4 and Week 5 counts to complete the graph.

Givens

Week 1 = 200 cars, Week 2 = 300 cars, Week 3 = 240 cars
Week 4 = Week 3 + 60
Week 4 + Week 5 = 700
Each small grid square = 20 cars

Unknowns

Number of cars made in Week 4
Number of cars made in Week 5

Constraints

Plotted Week 4 and Week 5 values must land on grid squares worth 20 each

#7 Identify Subproblems · also uses: #11 Work Backwards

I solve in order from what I can already know: first Week 4 (Week 3 plus 60), then Week 5 (the 700 total minus Week 4). Each is a one-step subproblem, and finding Week 5 uses the total backwards.

3 · Execute3 carry out the plan

1Find Week 4

#7 Identify Subproblems 4.OA.A.3

Week 4 is 60 more than Week 3, and Week 3 is 240, so Week 4 = 240 + 60 = 300.

240 + 60 = 300

Start from the value you already know and apply the given step.

2Find Week 5

#11 Work Backwards 4.OA.A.3

Week 4 and Week 5 together make 700, so Week 5 = 700 - Week 4 = 700 - 300 = 400.

700 - 300 = 400

Knowing the total and one part, subtract to recover the other part.

3Plot the points

#7 Identify Subproblems 5.MD.B.2

On the graph (each square = 20), Week 4 300 sits 0 squares above 300, and Week 5 400 sits 0 squares above 400; join the points with straight segments.

300 = 300 + 0\times 20,\quad 400 = 400 + 0\times 20

Converting the numbers into squares lets you place each point exactly.

Answer: Week 4 = 300 cars, Week 5 = 400 cars

4 · Reviewdoes it hold up?

Check the clues: Week 4 300 is indeed 60 more than Week 3 240, and Week 4 300 + Week 5 400 = 700 as required. Both values land neatly on grid lines (multiples of 20), so the plotted points are valid.

Another way: Convert to algebra (tool 13): let Week 4 = J = 240 + 60 and Week 5 = 700 - J; solving gives the same J = 300 and Week 5 = 400.
