Question

Genevieve wants to buy a laptop that originally cost p dollars. The laptop is on sale for $100 off. Genevieve also has a 15% off coupon. Write an expression for the price Genevieve will pay.

Answer 1

Answer:

Therefore, the resulting expression for the price Genevieve will pay

will be:  $p-100-\frac{3}{20}p$

Step-by-step Explanation:

Let the original cost of a laptop = p dollars

• As the laptop on sale for $100 off
• Genevieve also has a 15% off coupon

So, subtract the $100 and 15% off coupon (15% off on original 'p' cost)

The resulting expression for the price Genevieve will pay can be computed as:

$p-100-15\%\:p$

$=p-100-15\frac{p}{100}$

$=p-100-\frac{3}{20}p$        ∵ $15\%\mathrm{\:in\:fractions}:\quad \frac{3}{20}$

Therefore, the resulting expression for the price Genevieve will pay

will be:  $p-100-\frac{3}{20}p$
