64*3= 192 I multiplied that because the car traveled for 3 hours at the speed of 64 miles.
64-15= 49 I subtracted 15 out of 64 because the car only traveled 45 minutes after the three hours.
=241 final answer
you Need to think of 2 square numbers that add up to make 80
answer:
64 + 16
this means that x = 8 and y = 4

I would not buy the Iphone 7 because they did not take out the correct percent off. 25% would be .25, so .25 x 675=168.75 should be taken off the price to make it sale price $506.25.
The store had the computer take only 20% off of the price because:
675-540=135 for the amount they took off.
% x 675=135
%=135/675
%=.2 or 20%
