Given Parmesan cheese was on sale for $13.60 per pound
Welsey bought a piece of the parmesan cheese that weighted \frac{11}{8} pounds
we need to spend$13.60 for 1 pound
for [tex]\frac{11}{8} pound[/tex]
[tex]\frac{11}{8}\times 13.60=$18.72 [/tex]
So Wesley need to spend $18.70 to get the Parmesan cheese.
