Write and solve a system of equations for the situation described below. Define your variables and write your solution as a sentence. Homework Help ✎

Daria has all nickels and quarters. The number of nickels is $3$ more than twice the number of quarters. If she has $\1.90$ in all, how many nickels does Daria have?

$n=$ number of nickels
$q=$ number of quarters

so: $n=2q+3$ and
$\0.05n+\0.25q=\1.90$.
