The answer is "19.89".
Step-by-step explanation:
Given:

Solution:






that's why the answer is correct.
Set up a system of equations.
d + q = 75
.1d + .25q = 14.25
Multiply the first equation by -.1 so that the "d's" will cancel.
-.1d -.1q = -7.5
.1d +.25q = 14.25
Now add the two equations together
.15q = 6.75
divide both sides by .15
q = 45
There are 45 quarters in the jar
From the text of the task we can write the equation:
What a questions equals out to be.
