Lisa's store collects 5% sales tax on every item sold. If she collected $22.00 in sales tax, what was the cost of the item her store sold?

5% of sold is tax

22.00=tax

therefor

22.00=5% of total

5%=5/100=1/20

'of' means multiply

22.00=1/20 times totl

multiply both sides by 20/1 to clear fraction

440.00=total

cost of items is $440.00

22/0.05 = 440

therefore the cost of the item was $440

(5% of 440 = 22)
