### Question Description

Jake's BBQ sells its sauce for $10.75, including 8.5% tax. To the nearest penny, what is the cost of the sauce before tax?

Did I do this right?

1+0.085x=10.75

1.085x=10.75

10.75/1.085=9.907

$9.91

## Tutor Answer

Jake's BBQ sells its sauce for $10.75, including 8.5% tax. To the nearest penny, what is the cost of the sauce before tax?

$10.75-selling price

the selling price however includes the tax thus it is at 108.5%

$10.75=108.5%

? =100%

when you cross multiply

$10.75*100%/108.5%=$9.907

=$9.91

Your answer is correct.
