Question

14. a house-painting company charges 376$ plus 12$ an hour. Another painting company charges 280$ plus 15$ an hour.

A. how long for which both companies will charge the same amount?

B. What will the cost be?

Answer 1

One company charges:
$376 + $12*h

Other company charges:
$280 + $15*h

They will both charge the same when:

$376 + $12*h = $280 + $15*h

96 = 3*h

hours = 32
Cost will be $760

Double Check
$376 + $12 * 32 hours = $760

$280 + $15 * 32 hours = $760
