Can you plumber charges $12 for 15 minutes of work at this rate what would the plumber charge for one hour of work

Answer 1

Recall that 15 minutes is 1/4 of an hour. Since we know that he charges $12 for 15 minutes, we need to multiply his quarterly rate of $12 by 4 to determine how much he charges for one hour:

$12 * 4 = $48 per hour
