Using Multiple Representations to Solve Problems Review

A party store charges $18 for 6 foil balloons and $2 for each additional foil balloon. Let b = number of balloons. Let c = total cost ($). Looking at the table, which equation represents this situation? Select the equation & its simplified version.

• c = 2b + 16

• c = 2b + 6

• c = 2(b - 1) + 18

• c = 2(b - 1) + 6

A children’s museum charges $10 admission for the first visitor and $5 for each additional visitor in a group. Which equation represents this situation? Select the equation & its simplified version.

• c = 5(v - 1) + 10

• c = 5v + 10

• c = 5v + 5

• c = 10(v - 1) + 10

The zoo offers special admission rates for large groups of visitors. The zoo charges $8.60 admission for the first visitor and $6.00 for each additional visitor in the group. Which equation & its simplified version represent this situation? Let c = total cost ($) and let v = visitors.

• c = 6(v - 1) + 8.60

• c = 8.6(v - 1) + 6

• c = 8.6v + 2.6

• c = 6v + 2.6

• c = 6v - 2.6
