Question

the admission charge for a family at a museum is $7.50 for the first person and $4.25 for each additional member of the family. how many people are in a family if the total charge was 28.75?

Answer 1

7.50 + 4.25x = 28.75

subtract 7.50 from both sides

4.25x = 21.25

divide each side by 4.25

x = 5

answer: there are 5 people in the family
