Answer:
$3.039
Step-by-step explanation:
Step 1
They bought 2 pounds of paper hearts at $ 3.42 per pound
1 pound = $3.42
2 pounds =
2 × $3.42
= $6.84
2 pounds of sparkling stars for $ 3.93 per pound
1 pound of sparking stars = $3.93
2 pounds =
$3.93 × 2
= $7.86
5 pounds of shiny coils for $ 2.53 per pound.
1 pounds of shiny coils = $2.53
5 pounds =
5 × $2.53
= $12.65
Step 2
We find the total cost of the materials
Total cost of Materials that make up the confetti = Cost of paper heart + Cost of sparkling stars + Cost of shiny coils.
= $6.84 + $7.86 + $12.65
= $27.35
Step 3
Total pounds of materials bought = 2 pounds + 2 pounds + 5 pounds
= 9 pounds
Step 4
The cost per pound of confetti = Total cost of the materials bought/ Total pounds of materials
= $27.35/9
= $3.0388888889
Approximately ≈ $3.039
The cost per pound of the confetti = $3.039
The cost per pound of the confetti is $3.04
