Jamie bought a load of gravel to cover her driveway. her brother works for the gravel company and got her a 28% discount. if jamie paid $357.83 for the gravel (without tax), what would it have cost her without the discount?

without the discount, it would have cost her $497

Step-by-step explanation:

Let x represent the amount that the gravel would have cost her without the discount.

Her brother works for the gravel company and got her a 28% discount. The value of the discount would be

28/100 × x = 0.28 × x = 0.28x

It mans that the amount that she paid for the gravel is

x - 0.28x = 0.72x

If Jamie paid $357.83 for the gravel (without tax), it means that

0.72x = 357.83

x = 357.83/0.72

x = 496.99

Approximately $497
