Question

The coin container on a bus has 10 more nickels than dimes and together the nickels and dimes are worth $3.50. How many nickels and dimes are in the container?

Answer 1

so you add 10 nickels and then add the rest of the dimes

Answer 2

(10 + x)$.05 + $.10x = $3.50.

$.50 + $.05x + $.10x = $3.50.

$(.05 + .10)x = $(3.50 - .50).

$.15x = $3.00.

x = $3.00/$.15.

x = 20 dimes

So (20 + 10) nickels.
