Question

Suppose 3 friends each pay for a pair of socks and one 30-minutes jump. The jump costs $ 15.50 per person. If they spend a total of $ 60, then the equation 3(15.50 + x) = 60 can be used to find the cost x of the socks.

Answer 1

Explanation:

3(15.50 + x) = 60

46.5 + 3x = 60

3x = 60-46.5

x = 13.5/3

x = 4.5 or $4.50
