12-212.

Maia had 130 coins, all nickels, dimes, and quarters, in her change jar. Their value totaled $20.80 and she noticed that there were 15 more dimes than nickels. How many of each type of coin did she have? Homework Help ✎

Write 3 equations to describe the situation.

*n* + *d* + *q* = 130

0.05*n* + 0.10*d* + 0.25*q* = 20.80*n* + 15 = *d*
