Question

Jude has seven times as many dimes as nickels. Their value is $5.25. How many nickels does he have?

Answer 1

You have x nickels and 7x dimes (since you have 7 times more dimes than nickels)
You then add the values of each currency and total:
0.05*x + 7*0.10*x = 5.25
You can factor out the x to get:
x(0.05+.70) = 5.25 ---> Solving for x, the number of nickels, you get 7 nickels

Answer 2

so 7
