Roy earns $13 per hour and $7 for each table he constructs. If he wants to earn at least $170 today,what is the least amount of tables he must construct while working for 9 hours?
A) 5 tables.
B) 6 tables.
C) 7 tables.
D) 8 tables.
Please show the work

Respuesta :

9 hours * $13/hr = $117

$170 - $117 = $53

$53/$7 = 7.57

7.57 tables translates to 7 tables since you most likely won't be making just half a table. Therefore the minimum is at least 7 tables
