Question

the grocery store where you work sells green beans for 59c per pound. how much should you charge a customer for 5\frac{1}{2} pounds of green beans?

a $3.25
b. $3.54
c. $4.91
d. $6.09
e $9.32

Explanation:

Step1: Convert mixed - number to improper fraction

$5\frac{1}{2}=\frac{5\times2 + 1}{2}=\frac{11}{2}$

Step2: Multiply price per pound by weight

The price per pound is $0.59$. So the total cost $C=0.59\times\frac{11}{2}$.
$C = 0.59\times5.5=3.245\approx3.25$

Answer:

A. $3.25$
