31 lbs of bananas cost $248. How much would 40 lbs cost?
248 / 31 = 8 per pound
40 * 8 = ?
320
To find out how much 40 lbs of bananas would cost, we can set up a proportion based on the given information.
Let's assume that x represents the cost of 40 lbs of bananas.
We can set up the proportion as follows:
31 lbs / $248 = 40 lbs / x
To solve this proportion, we can cross-multiply:
31 lbs * x = 40 lbs * $248
Now we can solve for x:
31x = 40 * $248
Divide both sides of the equation by 31:
x = (40 * $248) / 31
By performing the calculation, we can find the answer:
x ≈ $320.65
Therefore, 40 lbs of bananas would cost approximately $320.65.
