Amount paid by Mary for her computer is \$800.

<u>Solution: </u>

Given that, Sam purchased a computer for \$800.

Price of the printer that Mary purchased was 40\% the price that Sam paid.

So, amount Mary pay for computer = Amount Sam paid for computer = \$800

Hence, amount paid by Mary for her computer is \$800.

Answer:


Step-by-step explanation:

the answer cannot be 5. Why? Because the minimum will occur when 12 and 5 point in opposite directions like both are on the x axis pointing to 0 from the east and pointing to zero coming from the west.

12 - 5 = 7

You cannot get a result less than that.
