Step-by-step explanation:
Given:
Ounces of peanut butter Wilhelmina has =
Number of sandwiches prepared by her =
According to the question:
She puts equal amount of peanut butter on each sandwiches.
So,
We have to find the quantity of peanut butter used for each sandwiches.
Here the distribution is equal so we have to use division method.
Let ounces of peanut butter applied on each sandwich be 'x'
⇒
⇒
⇒ Ounces
So each sandwich will get 1.66 ounces of peanut butter.
Answer:
Sabrina bought 3 pounds of bananas.
Step-by-step explanation:
Given equations are:
a + b = 8 Eqn 1
0.95a + 1.10b = 8.05 Eqn 2
As we have to find the number of pounds of bananas bought, we will eliminate the variable a from the equation.
Multiplying Eqn 1 by 0.95
0.95(a+b=8)
0.95a+0.95b=7.60 Eqn 3
Subtracting Eqn 3 from Eqn 2
(0.95a+1.10b)-(0.95a+0.95b)=8.05-7.60
0.95a+1.10b-0.95a-0.95b=0.45
0.15b = 0.45
Dividing both sides by 0.15
Hence,
Sabrina bought 3 pounds of bananas.
