6. Suzette has a total of 32 nickels and dimes. If
the total value of the coins is $2.45, find the
number of dimes she has.

Step-by-step explanation:

The answer is 85 32x5equals 160 then 245 minus 160 equals 85 85x10 equals 850 $8:50 plus $1:60 equals $2:45

17

Step-by-step explanation:

We can set this up by using an equation where D is the number of dimes and N is the number of nickels.

N x .5 + D x .10 = $2.45

N + D = 32

If we work our way through the equations, we find that D = 32 - N. We can plug this into the first equation and get N(.5) + .10(32-N) = $2.45

If we simplify the equation, we get 3.20-N(.5)=2.45, and thus N, or the number of nickels, equals 15.

If we go to the second equation and plug in N=15, we get 15+D=32. If we subtract 15 from both sides, we get D, or the number of Dimes, equals 17.
