Card 1

Question: Aron buys books online: the cost is $6 for each book plus a postage fee of $4. Write an expression for the total cost C for b books.

Answer: C = 6b + 4

Card 2

Question: Using C = 6b + 4, what is the cost for 6 books?

Answer: C = 6(6) + 4 = 36 + 4 = $40

Card 3

Question: Using C = 6b + 4, what is the cost for 12 books?

Answer: C = 6(12) + 4 = 72 + 4 = $76

Card 4

Question: Using C = 6b + 4, what is the cost for 3 books?

Answer: C = 6(3) + 4 = 18 + 4 = $22

Card 5

Question: Theatre tickets cost $12 each plus a booking fee of $3. Write an expression for the total cost C for t tickets.

Answer: C = 12t + 3

Card 6

Question: Using C = 12t + 3, what is the cost for 6 theatre tickets?

Answer: C = 12(6) + 3 = 72 + 3 = $75 (note: content listed $78, but expression gives $75).

Card 7

Question: Using C = 12t + 3, what is the cost for 4 tickets?

Answer: C = 12(4) + 3 = 48 + 3 = $51

Card 8

Question: Using C = 12t + 3, what is the cost for 10 tickets?

Answer: C = 12(10) + 3 = 120 + 3 = $123

Card 9

Question: Pizzas cost $24 each plus delivery of $5. Write an expression for the total cost C for p pizzas.

Answer: C = 24p + 5

Card 10

Question: Using C = 24p + 5, what is the cost for 8 pizzas?

Answer: C = 24(8) + 5 = 192 + 5 = $197 (content lists $192).
