Quizplus · Accepted Answer

Let the number of nickels be $n$ and the number of dimes be $d$. Given that $d = n + 2$. Each nickel is worth $0.05 and each dime is worth $0.10. The total amount is $1.70, so $0.05n + 0.10d = 1.70$. Substituting $d = n + 2$ into the equation gives $0.05n + 0.10(n + 2) = 1.70$. Solving this equation for $n$ gives $n = 10$, meaning she has 10 nickels.
