5 a craft store buys 50 yards of satin ribbon for $13.50. the store sells the ribbon by the foot. a customer can purchase 5 feet of ribbon for $0.80. how much profit does the craft store earn if it sells 45 yards of the ribbon and scraps the rest? show your work. answer
Answer
# Explanation:
## Step1: Convert yards to feet
Since 1 yard = 3 feet, 45 yards = 45×3 = 135 feet.
## Step2: Calculate selling - price
If 5 feet of ribbon sell for $0.80, then the selling - price per foot is $\frac{0.80}{5}=0.16$ dollars per foot. The selling - price of 135 feet is 135×0.16 = $21.6$.
## Step3: Calculate cost
The store bought 50 yards of ribbon for $13.50. The cost of the 45 yards of ribbon (assuming a proportional cost) is $\frac{45}{50}\times13.50 = 12.15$ dollars.
## Step4: Calculate profit
Profit = Selling price - Cost. So, profit = 21.6−12.15 = $9.45$.
# Answer:
$9.45$
