Linda has $6.90 worth of change in nickels and dimes. If she has 4 times as many nickels as dimes, how many of each type of coin does she have?

Question

I really really need this answer

Answer 1

I used a chart and the guess-and-check method to come up with the following

 

nickels     dimes       total $

100            25           7.50

96              24           7.20

92              23           6.90

 

So Linda has 92 nickels and 23 dimes.
