A hardware store has 200 paintbrushes. They order 9 boxes with 12 paintbrushes each. They sell 11 boxes that have 6 paintbrushes
grin007 [14]

Answer:

Step-by-step explanation:

The hardware store has 200 paintbrushes. They order 9 boxes with 12 paintbrushes each. This means that the total number of paintbrushes that was ordered is

12 × 9 = 108

Therefore, the total number of paintbrushes that the store has would be

200 + 108 = 308

They sell 11 boxes that have 6 paintbrushes each. This means that the total number of paintbrushes that they sold is

11 × 6 = 66

Therefore, the number of paintbrushes left would be

308 - 66 = 242

The manager's estimate is reasonable. They ordered about 120 paintbrushes and sold about 60 of them so they should have about 60 more paintbrushes than they started with.
