Answer:
The amount Kalasha would pay can be derived by taking off 10% and then subtracting $100;
[tex]\text{ \$710}[/tex]Explanation:
Given that the original price of the laptop is $900.
The store is offering 10% off on all computers.
So, we need to first take the 10% off the initial price.
[tex]\begin{gathered} =\text{ \$900}-10\text{\% of \$900} \\ =\text{ \$900-\$90} \\ =\text{ \$810} \end{gathered}[/tex]Kalesha has a $100 gift card.
Then we can now subtract the value of the gift card;
[tex]\begin{gathered} =\text{ \$810-\$100} \\ =\text{ \$710} \end{gathered}[/tex]Therefore, the amount Kalasha would pay can be derived by taking off 10% and then subtracting $100;
[tex]\text{ \$710}[/tex]
