Question

A company buys paper clips at the rate of $7.50 per box for the first 10 boxes, $5.50 per box for the next 10 boxes, and $3.50 per box for any additional boxes. How many boxes of paper clips can be bought for $221.00?

Answer 1

Answer:

46 boxes

Step-by-step explanation:

• First 10 boxes can be bought for $7.5*10=75$
• Next 10 boxes can be bought for $5.5*10=55$

So for a total of 20 boxes, the cost is $75+55=130$

We have remaining $221-130=91$

Each additional box costs 3.5, so for 91 dollars, we can get:

$\frac{91}{3.5}=26$ boxes

So, total $10+10+26=46$ boxes can be bought for $221.00
