Ariana has $1.40 worth of nickels and dimes. She has twice as many nickels as dimes. Determine the number of nickels and the number of dimes that Ariana has.

14 nickels

7 dimes

Step-by-step explanation:

1. find out how many dimes there has to be to get $1.40

1 dime= .10

1.40/.10=14 dimes

14/2=7

so there are 7 dimes

since a nickel is half the amount of a dime there will be twice as many to make up the other half which is $0.70

.70/.05=14

there are 14 nickels

proof:

$0.10(7)+$0.05(14)= $1.40

hope this helps!
