Solve the following using an equation

Question

Casey has $2.65 saved in nickels and quarters. She has 11 more nickels than quarters. Write a simplified equation that would allow her to find the number of nickels and quarters she has saved.

Answer 1

q = number of quarters at $0.25 each

q + 11 = number of nickels at $0.05 each

 

($0.25)q + ($0.05)(q + 11) = $2.65

 

0.25q + 0.05(q + 11) = 2.65

 

You can simplify the equation, solve for q and q + 11, and finish from here.
