Bananas are $0.49 per pound. What is the constant of proportionality and how much will 15 pounds of bananas cost?
I don't no the answer!!?
15 * .49
the constant of proportionality is the unit rate -- $/lb
so, since cost is in $, you need to multiply
$/lb * lb = $
To find the constant of proportionality, we need to determine the relationship between the weight of bananas and their cost. In this case, the relationship is a direct variation, since an increase in weight will result in a proportional increase in cost.
To find the constant of proportionality, we can take any given data point and use it to calculate the ratio between weight and cost.
Let's take the given price of bananas at $0.49 per pound. This means that for every pound of bananas, it costs $0.49.
So, the constant of proportionality is $0.49 per pound.
Now, to find the cost of 15 pounds of bananas, we can use the constant of proportionality. We multiply the weight (15 pounds) by the constant of proportionality ($0.49 per pound):
Cost = Weight × Constant of Proportionality
Cost = 15 pounds × $0.49 per pound
Therefore, 15 pounds of bananas will cost $7.35.
