Question 737801
I have ${{{9.45}}} in quarters and dimes in my pocket.
If there are {{{48}}} coins in all, there is {{{x}}} quarters and {{{48-x}}} dimes


{{{.10(48-x) + .25x = 9.45}}}

{{{4.8 - 0.10x + .25x = 9.45}}}

{{{ - 0.10x + .25x = 9.45-4.8}}}

{{{ .15x= 4.65}}}

{{{x = 4.65/.15}}}

{{{x = 31}}}................quarters

and dimes:

{{{ 48-31}}}

{{{ 17}}}................dimes
