Answer:
Step-by-step explanation:
Tito wants to buy some peanut butter to donate as much as possible.
There some brands are given with their price.
we will calculate the price of per ounce peanut butter of each brand.
A. Nutty : 12 ounces for $2.19
cost per ounce =
= $0.1825 ≈ $0.18 per ounce
B. Grandma's : 18 ounces for $2.79
cost per ounce =
= $0.155 ≈ $0.16 per ounce
C. Bee's : 0.28 ounces for $4.69
cost per ounce =
= $16.75 per ounce
D. Save-A-Lot : 40 ounces for $6.60
cost per ounce =
= $0.165 ≈ $0.17 per ounce
The lowest price is $0.16 per ounce. So he should buy Grandma's peanut butter.
This should help you here are the steps of your problem :)
2*(1/2)*r+2*r+1 = 9*(1/10) // - 9*(1/10)
2*(1/2)*r+2*r-(9*(1/10))+1 = 0
2*(1/2)*r+2*r-9/10+1 = 0
3*r+1/10 = 0 // - 1/10
3*r = -1/10 // : 3
r = -1/10/3
r = -1/30
r = -1/30
So your answer would be 1/30
