Question

Lin’s Father is paying for $50 meal. He has a $15 percent off coupon for the meal. What is the price of a discounted meal before the tax?

Answer 1

Note: Here tax rate is note given. Consider the tax is not applied.

Given:

Lin’s Father is paying for $50 meal.

Discount = 15%

To find:

The price of a discounted meal before the tax.

Solution:

Let x be the price of a discounted meal before the tax.

According to the question,

Price of meal after discount = Price of meal before discount - Discount

$50=x-\dfrac{15}{100}\times x$

$50=x-0.15x$

$50=0.85x$

Divide both sides by 0.85.

$\dfrac{50}{0.85}=x$

$58.823529=x$

$x\approx 58.824$

Therefore, the price of a discounted meal before the tax is $58.824.
