Apples cost $4 for 5lbs. How much will 40 lbs.of apples cost? (Set up a proportion and solve it)
4/5 = x/50
4/5 = x/40
To set up a proportion, we can compare the cost to the weight of the apples.
Let's assume x represents the cost of 40 lbs. of apples.
We can set up the proportion as follows:
$4 for 5 lbs = x for 40 lbs
This can be written as:
4/5 = x/40
To solve for x, we can cross multiply:
4 * 40 = 5 * x
Simplifying the equation, we have:
160 = 5x
To isolate x, we need to divide both sides of the equation by 5:
160 / 5 = 5x / 5
This gives us:
32 = x
So, 40 lbs of apples will cost $32.
