William earns $13 an hour working at a movie theater last week he worked h hours at the concession stand and three times as many hours at the ticket counter write and simplify an expression for the amount of money william earned last week

I think the expression for that is 13 • h • 3 because he gets $13 per hour and we don't know how many hours he worked so we would just put a variable and then he worked three times as many hours so multiply by 3. I might be wrong but hopefully it helps

The correct answer is $90
