Answer:
$5.33
Step-by-step explanation:
If there are 3 1/3 lbs of wood and it's $1.60 per lb, then:
Turn the mixed number into an improper fraction first:
3 1/3 = 3/3 + 3/3 + 3/3 + 1/3
= 10/3
Then, turn 1.60 into an improper fraction too:
1.6 = 1 6/10
= 1 3/5
= 5/5 + 3/5
= 8/5
Then—letting x represent the number of lbs:
8/5x = 8/5 × 10/3
= (8 × 10)/(5 × 3)
= 80/15
= 16/3
To put this in dollar/decimal form, simplify:
16 ÷ 3 = 5.3333333 . . .
≈ $5.33
