Question

C.

Minh and Mikayla are selling wrapping paper for a school fund-raiser. Customers can
buy either packages of folded paper or rolls of paper. Minh sold 6 rolls of paper and 2
packages of folded paper for a total of $44. Mikayla sold 3 rolls of paper and 9 packages
of folded paper for a total of $54. How much does each roll cost? How much does each
package of folded paper cost?

Answer 1

Rolls $6, Folded $4

Explanation:

Minh: 6r + 2f = 44

Mikayla: 3r + 9f = 54

Multiply Mikayla's x 2: 6r + 18f = 108

Subtract Minh: 6r + 2f = 44

16f = 64

f = 4, Folded paper is $4.

Substitute 4 for f into one of the equations.

6r + 2(4) = 44

6r + 8 = 44

6r = 36

r = 6 Rolled paper is $6
