a. estimated cost = $20

Exact value = $20.04

b. how much was his change from $50 = $29.96

Step-by-step explanation:

8 drill bits for $1.22 each = 8 * 1.22 = $9.76

10 washers for $0.11 each = 10 * 0.11 = $1.1

2 hammers for $4.59 each = 2 * 4.59 = $9.18

Total amount = $9.76 + $1.1 + $9.18

Total amount = $20.04

a. estimated cost = $20

Exact value = $20.04

b. how much was his change from $50 = 50 - 20.04 = $ 29.96
