Question 940892

The total cost of a USB drive and a printer was $225.50. If the cost of the USB drive is $170.70 less than the printer , what was the cost of each item?
<pre>
Let cost of printer, be P
Then cost of USB drive = P - 170.7
We then have: P + P - 170.7 = 225.5
2P = 225.5 + 170.7
2P = 396.2
P, or cost of printer = {{{396.2/2}}}, or ${{{highlight_green(198.10)}}}
Cost of USB drive: $198.10 - 170.7, or {{{highlight_green(27.40)}}}
