Answer:
11 pounds of cashew nuts
Step-by-step explanation:
To solve this problem, we call:
p = number of pounds of peanuts bought
n = number of pounds of cashew nuts bought
We also know that:
- Each pound of peanuts costs $2.75, so the cost of p pounds of peanuts is
- Each pound of cashew nuts costs $3.25, so the cost of n pounds of cashew nuts is
So the total cost, which in this case is $49.50, can be written as:
(1)
We also know that the total number of pounds is 16, so:
(2)
From this equation we get
And substituting into (1), we find n:
So, 11 pounds of cashew nuts.
