Question

3. Sarah gave her customers a 15% discount

for their meal on every first Thursday of
the month. If Karen paid $28.90 for her
meal with the discount how much was
her meal without the discount?

Answer 1

$34

Explanation:

Let x be the amount of meal without discount

Given.

Sarah gave her customers a 15% discount, that is equal to
`x*(15)/(100) =0.15x`

And discounted amount of meal is given, that is $28.90

The equation of discounted amount of meal is

`28.90=x-0.15x\\28.90=0.85x\\x=(28.90)/(0.85)\\x=34`

The amount of meal without discount is $34
