Problema Solution
Bob has 2 times as many dimes as nickels and the value of the dimes is 4.65 more than the value of the nickels. How many dimes and nickels does he have.
Answer provided by our tutors
1 nickle = 5 cents
1 dime = 10 cents
let
n = the number of nickles that Bob has
d = the number of dimes that Bob has
Bob has 2 times as many dimes as nickels
d = 2n
the value of the dimes is $4.65 more than the value of the nickels
10d = 465 + 5*n
by solving the system of equations
d = 2n
10d = 465 + 5*n
we find
d = 62 dimes
n = 31 nickles
