Question

Rachel has a coupon for 15% off her total lunch bill before tax.if t. represents the total cost of her lunch items before tax, which of these expressions represents the saving from the coupon?​

Answer 1

For this case we have the following variable:

• t: total cost of the account before the discount

The total discount percentage is 15%.

For this you must write the amount that is saved by the coupon.

We have then:

`\frac {15} {100} t`

Rewriting the expression we have:

`0.15t`

Answer:

The expression that represents the saving of the coupon is:

`0.15t`
