Answer:
0.75 (75%) of a bag
Step-by-step explanation:
The question states that Frank has 3 bags and 4 bird feeders. In order to know how much of the bags he needs to add to each feeder, we are going to need to divide the amount of bags by the amount of feeders. This in term will give us an equal amount that should be added to each feeder. ... simplify We see from the calculation above that each feeder will get an equal amount of 0.75 (75%) of a bag.

Answer:
14 quarters and 28 nickels
Step-by-step explanation:
System of Equations where x = number of quarters and y = number of nickels
(1) equation with value of each coin
0.25(x)+0.05(y) = 4.90
(2) total number of coins
x + y = 42
Solve system of equations using either substitution or elimination
(elimination multiplying equation 2 by -0.5)
.25(x) + 0.05(y) = 4.90
-0.05(x) - 0.05(y) = 42 * (-0.05)
(3) Resulting equation
.20(x) = 2.8
x = 14
plug x into equation 2
14 + y = 42
y = 28
There are 14 quarters and 28 nickels in Mary's collection.
I believe this is how you solve it
