\(3.3 \) Dimes and Quarters
Jada had some dimes and quarters that had a total value of \( \$ 12.50 \) . The relationship between the number of dimes, \( d \) , and the number of quarters, \( q \) , can be expressed by the equation \( 0.1 d + 0.25 q = 12.5 \) .
3. Is the number of dimes a function of the number of quarters? If yes, write a rule (that starts with \( d = \ldots . \) ) that you can use to determine the output, \( d \) , from a given input, \( q \) . If no, explain why not.
