Answer:
The correct answer is a) 10 lb
Step-by-step explanation:
We know that 3 lb of apples cost $2.40
We also know that exists a linear relationship between the cost and the amount of apple. We also know that this relationship is a direct linear relationship. This means that If we buy more apples the cost will increase.
To find the amount of apple that we can buy with $8.00 we can write :
\(\frac{2.40}{3}=\frac{8.00}{x}\)
The division between the cost of the apples and the amount of apples must be a constant.
$2.40 divided by 3 lb must be equal to $8.00 divided by ''x''
Solve it for x :
\(x=\frac{(8.00).(3)}{2.40}=10\)
The answer is x = 10 lb
Therefore, the correct options is a)
