as part of a spring clearance a men's store put dress shirts on sale, 2 for 25.30 how much will a business man pay if he buys 7 shirts

He charged $75 for an hour. He then charges $25 for additional hours.

The equation for that would be: 75 + 25h = x

x = the final price. h = every our after the first hour.

So, for 1 hour he charges $75.

For 2 hours he charges $100.

For 3 hours he charges $125.

For 4 hours he charges $150.

For 5 hours he charges $175. And so on.
