Difficulty: EasyUnit Price Comparisons

A supply clerk is comparing prices for standard issue notebooks. Vendor A sells a pack of 55 notebooks for 15.0015.00 dollars. Vendor B sells a bulk box of 2020 notebooks for 48.0048.00 dollars. What is the savings per notebook, in dollars, if the clerk chooses Vendor B instead of Vendor A?

Answer: 0.6 dollars

Answer

0.60
The unit price is found by dividing the total cost by the quantity. Vendor A charges 15.00÷5=3.0015.00 \div 5 = 3.00 dollars per notebook. Vendor B charges 48.00÷20=2.4048.00 \div 20 = 2.40 dollars per notebook. The savings per notebook is the difference: 3.00−2.40=0.603.00 - 2.40 = 0.60 dollars.

Step-by-Step Solution

1
Calculate Vendor A's unit price
3.003.00 dollars per notebook
To find the cost of a single item in a package, divide the total price by the number of items (15.00÷515.00 \div 5).
2
Calculate Vendor B's unit price
2.402.40 dollars per notebook
Divide the bulk box total price by the number of notebooks it contains (48.00÷2048.00 \div 20).
3
Calculate the difference between the two unit prices
0.600.60 dollars
Subtracting Vendor B's unit price from Vendor A's unit price (3.00−2.403.00 - 2.40) gives the exact savings per notebook.
