15. Empire School bought new computers and printers. The computers and printers together cost $1600. The printers cost $350. If the cost of the computers is ‘c’ dollars, this equation could be used to find the cost of the computers. • 350 – c = 1600 • 350 + 1600 = c • 350 + c = 1600 • 350 ÷ c = 1600

16. What is C. 350 + c = 1600?

17. Joan bought 5 cans of pop which cost a total of $10. If ‘p’ represents the cost of one can of pop, this equation could be used the find the cost of one can. • 5 + p = 10 • 5 – p = 10 • 10 – 5 = p • 10 ÷ 5 = p

18. What is D. 10 ÷ 5 = p?

19. A cheese pizza costs $7. Each topping has an additional cost. This table shows the cost of a cheese pizza with additional toppings. Number of Toppings (n) Total Cost of the Pizza (c) • This equation below represents the situation. • c = n + 2 • c = n + 8 • c = (2 + n) + 7 • c = 2n + 7

20. What is D. c = 2n + 7?

21. This equation below shows the relationship between x and y in the table above. • x + 8 = y • 3x - 4 = y • 2x + 3 = y • x + 13 = y

22. What is C. 2x + 3 = y?
