Question

A stuffed heart toy costs 20.00. After Valentines Day, the toy is discounted by 1/4. The customer paid with their store credit card to receive an additional 1/10 at the register. Which expression can you use to find the total discount this customer receives

Answer 1

Find out the total discount this customer receives.

To proof

As given in the question

A stuffed heart toy costs $20.00

After Valentines Day

`Discount\ (1)/(4)\ is\ given`

and

`customer\ receive\ an\ additional\ (1)/(10)\ at\ the\ register`

than the expression becomes

`=20 -(1*20)/(4)- (1*20)/(10)`

= 20 - 5 - 2

= $13

Total discount becomes

`= (1*20)/(4) +(1*20)/(10)`

= 5 +2

= $7

than the total discount becomes is $7 .

Hence proved
