A coin jar is full of quarters and dimes and has a total value of $17.40. The number of quarters in the jar is 5 more than 3 times the number of dimes. How many quarters and dimes are there ?

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
