A mechanic charge $75 for up to 1 hour of work. for each additional hour, he charges $25.

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.

He charges 100 dollars for two hours?
