Solve for variable: 2(r-3)/4 -8 =50

Hello!

Let's begin by multiplying all 3 terms by 4, to remove the fraction:

2(r-3) - 8(4) = 50(4)

Then 2r - 6 - 32 = 200. Consolidating the constants on the right side, we get:

2r = 162. Solving for r, we divide both sides by 2, obtaining r = 81 (answer)

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
