Question

Cindy goes to the market and spends $15 on 2 lbs of apples and 3 lbs of grapes. The grapes cost $2.45 per pd.

Answer 1

Answer:

The apples cost $3.82 per pounds.

Step-by-step explanation:

We are given the following in the question:

Cost of grapes = $2.45 per pd

Total money spent = $15

Total purchasing = 2 lbs of apples and 3 lbs of grapes

Total cost of grapes =

$=\text{Cost of grapes}\times \text{Amount of grapes}\\= 2.45\times 3 = 7.35$

Total cost of apples =

$\text{Total cost} - \text{Total cost of grapes}\\= 15 - 7.35 = 7.65$

Cost of apple =

$= \dfrac{\text{Total cost of apple}}{\text{Amount of apple}}\\\\= \dfrac{7.65}{2} = 3.825\ \text{ per pound}$

Thus, the apples cost $3.82 per pounds.

Answer 2

Answer: one pound of apple costs $3.825

Step-by-step explanation:

Let x represent the cost of one pound of apple.

Total amount spent on 2 lbs of apple and 3 lbs of grapes is $15

The grapes cost $2.45 per pound. This means that the total cost of 3 lbs of grapes would be

2.45 × 3 = $7.35

Since Cindy spent a total of $15, it means that

2x + 7.35 = 15

Subtracting 7.35 from both sides of the equation, it becomes

2x + 7.35 - 7.35 = 15 - 7.35

2x = 7.65

x = 7.65/2 = $3.825
