Quarters = x
dimes = 196 - x
10(196 - x) + 25x = 3940
1960 - 10x +25x = 3940
1960 + 15x = 3940
15x = 1980
x = 132
169 - 132 = 64
Therefor there are 132 quarters and 64 dimes

Answer:
C) 4
Step-by-step explanation:
Given equation:

The above equation represents proportional relationship.
To find the constant of proportionality.
Solution:
<em>The equation representing proportional relationship is given by:</em>
<em>
</em>
<em>where
represents constant of proportionality.</em>
So, in order to find the value of
for the given proportionality relationship, we will solve for 
We have:

Solving for 
Dividing both sides by 2.


∴ 
Thus, the constant of proportionality = 4.
