Leonardo makes the following purchases at the store:1 backpack for $16.895 spiral notebooks for $1.19 each1 pack of mechanical pencils for $3.682 packs of lead refills for $1.88 eachLeonardo has 2 coupons, each for 45 cents off on the purchase of a pack of lead refills. The coupons are applied after tax and the sales tax is 5% of the purchase. If Leonardo paid $30.89 , then he _____ for his purchase.
The purchases total $16.89 + (5 × $1.19) + $3.68 + (2 × $1.88) = $30.28. The 5% sales tax is $1.514, which rounds to $1.51, making the taxed total $31.79. The two coupons take off $0.90 after tax, so Leonardo owes $30.89 and paid the correct amount.
