Questions: A company buys pens at the rate of 7.50 per box for the first 10 boxes, 5.50 per box for the next 10 boxes, and 4.50 per box for any additional boxes. How many boxes of pens can be bought for 148.00? 24 27 19 31 21

Solution Steps

The cost of the first 10 boxes is: \[ 10 \times \$7.50 = \$75.00 \]

The cost of the next 10 boxes is: \[ 10 \times \$5.50 = \$55.00 \]

The total cost for the first 20 boxes is: \[ \$75.00 + \$55.00 = \$130.00 \] The remaining budget is: \[ \$148.00 - \$130.00 = \$18.00 \]

The cost per additional box is \$4.50. The number of additional boxes that can be purchased is: \[ \frac{\$18.00}{\$4.50} = 4 \text{ boxes} \]

The total number of boxes is: \[ 10 + 10 + 4 = 24 \text{ boxes} \]
