Orlando is mixing nuts and cereal squares to make a party mix. Nuts sell 7$ a pound and cereal squares sell for 4$ a pound. If O
rlando wants to make 30 pounds of party mix at a cost of $6.50 a pound, how many nuts and cereal squares should he use?
1 answer:
Answer:
25 pounds of nuts and 5 pounds of cereal squares.
Step-by-step explanation:
Let amount of nuts be x and cereals squares be y pounds.
x + y = 30
7x + 4y = 30*6.5
7x + 4y = 195 Multiply the first equation by -4:
-4x - 4y = -120 Adding:
3x = 75
x = 25 pounds.
y = 30 - 25 = 5 pounds.

First make the equation:
1. x
2. 3x
x + 3x = 48
Now solve it:
x + 3x = 48
4x= 48
x=12
Now plug in x
1. x = 12
2. 3x = 36

Estimate of 428,731 - 175,842 = 400,000 - 200,000 = 200,000
