we know that
Carrie buys [tex] 4.16 [/tex] pounds of apples for $[tex] 5.20 [/tex] how much does [tex] 1 [/tex] pound cost
by proportion
[tex] \frac{5.20}{4.16} \frac{dollars}{pound} =\frac{x}{1} \frac{dollars}{pound} \\ \\ x=\frac{5.2}{4.16} \\ \\ x=1.25\ dollars [/tex]
therefore
the answer is
The cost of one pound is equal to [tex] 1.25\ dollars [/tex]
