A store sells wrapping paper for $3, greeting cards for $2, and ribbon for $1. The soccer team buys 15 rolls of wrapping paper, 10 greeting cards, and 12 rolls of ribbon.
a. Write an expression to find the total cost of the soccer team's purchase.
b. How much did the soccer team spend?

A) (15 x $3) + (10 x $2) + (12 x $1) = X

B) $77      

Step-by-step explanation:

A) Each wrapping paper is 3 dollors, and they bought 15 (15 x 3)

Each greeting card is 2 dollors, and they bought 10 (10 x 2)

Each roll of ribbon is 1 dollors, and they bought 12 (12 x 1)

B) 15 times 3 is 45

10 times 2 is 20

12 x 1 is 12

45 + 20 + 12 = 77

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
