Question

at the fabric store where you work, a customer wants to buy 9\\(\frac{1}{2}\\) yards of ribbon that costs $0.98 per yard. before adding sales tax, how much will the ribbon cost?\
\
a $4.41\
\
b $8.52\
\
c $9.31\
\
d $9.80\
\
e $10.48

Explanation:

Step1: Convert mixed number to improper fraction

The length of the ribbon is \( 9\frac{1}{2} \) yards. Convert this to an improper fraction: \( 9\frac{1}{2}=\frac{9\times2 + 1}{2}=\frac{19}{2} = 9.5 \) yards.

Step2: Calculate total cost

The cost per yard is \$0.98. To find the total cost, multiply the length (in yards) by the cost per yard: \( \text{Total Cost}=9.5\times0.98 \).
Calculate \( 9.5\times0.98 \):
