The scouts are putting on a crab feed. They have sold 79 adult tickets and 52 child tickets. Adult tickets cost $41 and child tickets cost $19. The
scout leader estimates that they have sold around $7,000 worth of
tickets. Is that a good estimate?

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

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
