Answer:
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
