Answer:
The cost of 6 pounds of apples would be $ 7.50
Step-by-step explanation:
4 pounds of Apple cost = $ 5
8 pounds of Apple cost = $ 10
Cost of apples(y) varies directly with the number of pounds of apples(x), so we can express this as:
[tex]y \propto x[/tex]
Introducing the constant of proportionality, we get:
[tex]y=kx[/tex]
Using, y = 5 and x =4, we get:
[tex]5=4k\\\\ k = 1.25[/tex]
Thus, the relation between y and x will be:
y = 1.25x
So, for 6 pounds of apples, we have x = 6. Using this value in above equation, we get:
y = 1.25 x 6
y = $ 7.50
Thus, the cost of 6 pounds of apples would be $ 7.50
