How much would it cost with shipping if someone ordered 1 CD?

• $4.50

• $4.62

• $12

• $16.50

How much would it cost with shipping if someone ordered 2 CDs?

• $9

• $21.00

• $24.00

• $28.50

How much would it cost with shipping if someone ordered 3 CDs?

If you know how many CDs Mickey orders, can you determine how much money he spends? Write a corresponding equation. Use C to represent "cost" and D to represent the number of CDs Mickey orders.

• C = 4.5D + 12

• C = 12D + 4.5

• D = 4.5D + 12

• D = 12D + 4.5

Use an equation to determine how much money Mickey would spend on 8 CDs.

• $24.50

• $48.00

• $96.00

• $100.50

How much would it cost with shipping if the class ordered 1 book?

• $2.95

• $6.95

• $9.90

• $12.85

How much would it cost with shipping if the class ordered 2 books?

• $10.95

• $6.95

• $9.90

• $12.85

How much would it cost with shipping if the class ordered 3 books?

• $14.95

• $6.95

• $9.90

• $12.85

If you know how many books Mr. Gee's class orders, can you determine how much money they spend? Write a corresponding equation. Use C to represent "cost" and B to represent the number of books Mr. Gee's class orders.

• C = 2.95B + 4

• C = 4B + 2.9

• B = 2.95C + 4

• B = 4C + 2.9

Use an equation to determine how much Mr. Gee's class spent on 24 books.

• $70.80

• $74.80

• $96.00

• $98.95
