Question

How should kelesha determine the amount she will pay for her computer?

Answer 1

Given:

The original price of the computer, CP = $900.

The discount rat offered on all computers, R=10%

Kalesha has a $100 gift card.

The discount is applied on the original price of the computer. So, Kalesha should first take 10% off and then only subtract $100 from it.

Therefore, the answer is " Take 10% off, then subtract $100.

The discount amount for the computer is calculated as,

`\begin{gathered} D=(R)/(100)* CP \\ =(10)/(100)*900 \\ =90 \end{gathered}`

Now, the amount after taking 10% off is,

`\begin{gathered} A=CP-D \\ =900-90 \\ =810 \end{gathered}`

There is a $100gift card. So, the final amount that Kalesha should pay can be calculated as,
