Julia bought

pounds of potatoes and

pounds of carrots. Which expression can be used to find how many pounds of vegetables Julia bought?


Sagot :

Answer:

t = cx + py

Step-by-step explanation:

First, apply variables to each factor:

The number of carrots bought = c

The number of potatoes bought = p

The weight (in pounds) of one carrot = x

The weight of one potato = y

Now that we've assigned variables to each piece of this equation, let's put it together.

Each vegetable has a weight, and Julia bought a certain number of each one. If she bought p potatoes, we'd multiply that by the weight of a single potato (y) to get the total weight potatoes. That is represented by the equation:

total potato weight = py

Since we are looking for the total weight of all the vegetables she bought (t), we must make a larger equation demonstrating both the weight of the carrots and the potatoes.

t = cx + py

This equation is correct because cx represent the total weight of the carrots (weight of one carrot * number of carrots bought) and the same is true for py and potatoes.
