- Following the order of operations, we do parenthesis first.

- Multiply out the value against the parenthesis.

- This leaves us with 20 over 20. 20 goes into 20 only 1 time, so our final answer is 1.
Answer:
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%
