During a sale, $2 bars of soap were sold of a rate of 3 for $5. how much is saved on 9 bars ?

3 dollars is saved on 9 bars

Step-by-step explanation:

Original price of one bar soap is $2

Original cost of 3 bars would be 2×3 = $6

But it was sold at a rate of 3 bars for $5. Amount of money saved on 3 bars would be 6 - 5 = $1

If another 3 bars are bought for $5, the amount saved will be $1 again.

If 3 extra bars are bought for $5, the amount saved will be $1

Total number of bars bought is 3 + 3 + 3 = 9

Total amount saved = 1 + 1 + 1 = $3

Checking,

3 bars = $5

9 bars = (9×5)/3 = $15

Originally, 9 bars = 9×2 =$18

Amount saved = 18 - 15 = $3
