Question

A manager is comparing the cost of buying ball caps with the company emblem for two different companies.

Company X charges a $50 fee plus $7 per cap.
Company Y charges a $30 fee plus $9 per cap.
For what number of ball caps will the manager's cost be the same for both companies?

Answer 1

Let c = the number of ball caps

Company X: y = 7c + 50

Company Y: y = 9c + 30

9c + 30 = 7c + 50

2c = 20

c = 10 caps
