[nycmathguy]

The computer Jack needs to buy is selling for $1,200.00. He only have 65% of the cost. How much more will Jack need to make the purchase?

The cost is 1200. He has 0.65 of 1200.

So, (0.65)(1200) = 780.

Jack has $780.

Let m = the amount if money Jack needs to buy the computer.

m = $1200 - $780

m = $420.

Jack needs $420 to purchase the computer.
