Lisa purchased a hat for $10, a purse for $20, and a book for $23.the sales-tax rate was 7.2 percent. what was the total amount she paid?

Here is the solution on how much the total amount that Lisa paid:The total amount for all the items is $53:  $10 + $20 + $23 = $53 Now, 7.2% = 0.072 Compute for the sales tax of each item:$10 x 0.072 = .72 $20 x 0.072 = 1.44 $23 x 0.072 = 1.66 The total sales tax would be: .72 + 1.44 + 1.66 = $3.82 Now add the Sales tax to the total price of the items. $53 + 3.82 = $56.82Therefore, Lisa paid $56.82.
