at Tim eats soup for dollar2 a can he bought 40 cans with 30% how much money did he spend
If he bought 40 cans at FULL price he paid $2 x 40 = 80 dollars.
If he had 30% OFF he paid 80 - 80(30%) = 56 Dollars
If he paid only 30% of the original price He paid 80 (30%) = 24 dollars
Not sure which scenario you are asking about......
