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

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
