Ethan bought a printer on sale for $59.99 and a jump drive for $6.99. the sales tax on the total was $5.36. Ethan gave the sales person four $20 bills. how much change did Ethan receive?

7.66

Step-by-step explanation:

Add up the total cost, the prices of the items and the tax

59.99+6.99+5.36 =72.34

He gave the sales person 4*20 = 80

Subtract the cost from the  money paid

80 - 72.34 = 7.66
