Answer:
Cost 0.70 per pound.
Step-by-step explanation:
If you see the cost and the weight you can get the price per pound, so if 5 pounds cost $3.50, you can evaluate doing a rule of three:
[tex]\frac{3.50}{5}=\frac{x}{1}[/tex]
So if you clear X you´d get this:
[tex]x=\frac{(3.5)(1)}{5}[/tex]
[tex]x=0.70[/tex]
So the cost per pound is $0.70.
Now that you have the cost per pound you can do the equivalent ratios:
Cost---------------Apples
0.70---------------1 pound
3.5--------------- 5 pounds
7--------------- 10 pounds
