kalesha is purchasing a laptop. the original price of the laptop is $900. the store is offering 10% off on all computers. kalesha has a $100 gift card.how should kalesha determine the amount she will pay for her computer? subtract $100, then take 10% off. take 10% off, then subtract $100.kalesha will pay    the answer is : $710

The amount Kalesha will pay for her computer is:

                      $ 710

It is given that:

The original price of the laptop is $900.

The store is offering 10% off on all computers.

Kalesha has a $100 gift card.

Now in order to calculate the amount Kalesha will pay we first have to find the cost that will be reduced on a offer of 10% provided by the store and subtract this reduced price from the original price ; and finally we again subtract $ 100 from this resulting price.

When a offer of 10% is applied to the computer we have:

Price reduced on offer=10% of original price

i.e.

Price reduced on offer=10%×900

i.e.

Price reduced on offer=0.10×900

i.e.

Price reduced on offer=$ 90

Cost of Computer= Original price-Price reduced on offer

i.e.

Cost of computer= 900-90

i.e.

Cost of Computer=$ 810

Now, when Kalesha uses her gift card of $ 100 then,

Amount Kalesha will pay= $ (810-100)

i.e.

Amount Kalesha will pay= $ 710
