The needed equation is: 3 x + 2 y = 20

Step-by-step explanation:

Here, the given question is incomplete.

Susheila is making a large batch of granola to sell at a school fundraiser.

She needs to buy walnuts and almonds to make the granola. Walnuts cost $3 per pound, and almonds cost $2 per pound. She has $30 to spend on these ingredients.

a. Write an equation that represents the different amounts of walnuts, x,

and almonds, y, that Susheila can buy.

Here, as given in the question:

The cost of per round of walnuts = $3

⇒The cost of buying x rounds of walnuts = x (cost of 1 round of walnuts)

= x (3) = 3 x

The cost of per round of almonds = $2

⇒The cost of buying y rounds of almonds = y (cost of 1 round of almonds)

= y (2) = 2 y

So, the total cost of buying x rounds of walnuts + y rounds of almonds

= Cost of x rounds of walnuts + cost of y rounds of almonds

= 3 x + 2 y

Also, the amount she can spend on ingredients = $30.

So, the needed equation is:

3 x + 2 y = 20
