Worked Solution
Step 1: Multiply the whole dollars: $3 × 6 = $18.
Step 2: Multiply the cents: $0.45 × 6.
— 5 hundredths × 6 = 30 hundredths = $0.30
— 4 tenths × 6 = 24 tenths = $2.40
— Total cents portion: $0.30 + $2.40 = $2.70
Step 3: Add: $18 + $2.70 = $20.70.
(Alternatively: 345 × 6 = 2070; place decimal to get $20.70.)
Answer: $20.70
Correct answer: $20.70
