Question

Jeff has $3.15 made up of nickels and dimes. If he has five times as many nickels as dimes,how many dimes does he have? show let statements and equations.

Answer 1

The equation will be based off of the dimes.
d= number of dimes
.1d+ 5d(.05)=3.15
.35d=3.15
d=9
There are 9 dimes, so there must be 45 nickels since there are 5 times as many.
Check your answer:
9(.1)+45(.05)=.9+2.25=3.15
There are 9 dimes and 45 nickels.
