8. A woman buys three pairs of jeans for $99.84, including tax. If each pair of jeans cost $32, what was the sales tax rate?
:
Let x = sale tax rate (in decimals)
;
Find the cost for the jeans: 3 * 32 = 96; (which you did)
:
Tax + purchase = $99.84
96x + 96 = 99.84
:
96x = 99.84 - 96
:
96x = 3.84 (you got tax amt OK)
x = ;(you found the amt of tax for each pair of jeans, not the tax rate)
x = .04; 4% sales tax rate
;
:
Check solution
.04(96) + 96 =
3.84 + 96 = 99.84
