Trey went to the Five and Below and bought fake toilet paper for $3.75. He had a coupon for 50% off and there was a discount of 20%. After both of the discounts, there was a 10% tax. How much was the fake toilet paper? the answer has to have 6 steps in order to be correct​

turn all % into decimals ( ÷ 100 )

COUPON

0.5 x 3.75 = 1.875

round to the nearest hundredth: 1.90$

3.75 - 1.90 = 1.85$ NEW PRICE

DISCOUNT:

1.85 x 0.2 = 0.37

1.85 - 0.37 = 1.48$ NEW PRICE

TAX: STEP

0.1 x 1.48 = 0.148

round to the nearest hundreth = 0.50$

0.50 + 1.48 = 1.98$ NEW AND FINAL PRICE
