A business buys invoice forms at a cost of $4.45 a box for the first 20 boxes, $4.00 a box for the next 25 boxes, and $3.75 a box for any additional boxes. How many boxes of invoice forms can be bought for $234.00
Let's break it down step by step.
For the first 20 boxes, the cost is $4.45 per box. Therefore, the total cost for the first 20 boxes is 20 * $4.45 = $<<20*4.45=89.00>>89.00.
Next, we move on to the next 25 boxes. The cost for each of these boxes is $4.00. Therefore, the total cost for these 25 boxes is 25 * $4.00 = $<<25*4=100.00>>100.00.
Now we need to calculate the remaining cost for the rest of the boxes. We subtract the cost of the first 20 and next 25 boxes from the total amount given, which is $234.00 - ($89.00 + $100.00) = $<<234-(89+100)=45>>45.00.
Lastly , to find out how many boxes can be bought for $45.00, we divide the remaining cost by the cost per box, which is $3.75. So, the number of boxes we can get for $45.00 is $45.00 / $3.75 = 12 boxes.
Therefore, in total, the business can buy 20 + 25 + 12 = <<20+25+12=57>>57 boxes of invoice forms for $234.00.
