Asked by robin

you find a sales receipt from a store that shows the total price as $40, and the total amount paid including sales tax as $42.

a. Write an equation you can use to find the sales tax rate r.

b. Can you use r to find the percent for the sales tax?
Answered by bobpursley
rate=tax/price=(42-40)/2
percent= r*100
