the beach is 141 miles your gas tank holds 16 gallons and you use 3/8 of a tank to get there what is your miles per gallon and how much did it cost you to get there $3.15 per gallon?

23.5 miles a gallon, and $18.90 trip cost.

Step-by-step explanation:

16 is the full tank, and 6 is 3/8ths of that, so 6 gallons were used during the trip.

Miles per gallon:

141/6 = 23.5

The fuel mileage was 23.5 miles a gallon.

Cost:

6 * 3.15 = 18.9

The cost of the trip was $18.90.

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
