Brad have 19 quarters and 27 nickels.
Step-by-step explanation:
Given,
Total worth of nickels and quarters = $6.10 = 6.10*100 = 610 cents
One quarter = 25 cents
One nickel = 5 cents
Let,
x represent the number of quarters.
y represent the number of nickels.
According to given statement;
25x+5y=610 Eqn 1
y = x+8 Eqn 2
Putting value of y from Eqn 1 in Eqn 2
![25x+5(x+8)=610\\25x+5x+40=610\\30x=610-40\\30x=570](https://tex.z-dn.net/?f=25x%2B5%28x%2B8%29%3D610%5C%5C25x%2B5x%2B40%3D610%5C%5C30x%3D610-40%5C%5C30x%3D570)
Dividing both sides by 30
![\frac{30x}{30}=\frac{570}{30}\\x=19](https://tex.z-dn.net/?f=%5Cfrac%7B30x%7D%7B30%7D%3D%5Cfrac%7B570%7D%7B30%7D%5C%5Cx%3D19)
Putting x=19 in Eqn 2
![y=19+8\\y=27](https://tex.z-dn.net/?f=y%3D19%2B8%5C%5Cy%3D27)
Brad have 19 quarters and 27 nickels.
