A blender was originally sold for $90 and has been marked down to $79.20. What is the percentage of discount for the

blender?

88%

Step-by-step explanation:

From the question given above, the following data were obtained:

Original amount = $ 90

Discounted amount = $ 79.20

Percentage of discount =?

Let the percentage of discount be y %

Thus, we can obtain the value of y as follow:

y /100 × 90 = 79.20

90y /100 = 79.20

Cross multiply

90y = 100 × 79.20

90y = 7920

Divide both side by 90

y = 7920/90

y = 88

Thus, the percentage discount of the blender is 88%

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
