Question

Tyrone works at a diner,as a cashier and host. He earns $7.95 per hour no matter which job he does. Tyrone wants to buy a new guitar that costs $238.50. The manager of the diner needs him to work for 18 hours as a cashier next week. If Tyrone wants to buy the guitar next week , how many hours would he need to work as a host.

Answer 1

$7.95 x h = $236.50
$7.95 x 18 = $143.10

$236.50 - $143.10 = $93.4
7.95 x h = $93.4
$93.4 / $7.95 = 11.7 hours

h = 12 hours
