there are many ways to answer this problem. you can use portions and you can change the percent to a decimal.

the portions way is you do 60/100 = x/80

you do cross multiply so 60*80 and you get 4800 then you divide by 100.

or the easier way you convert the percent to a decimal and the you multiply it with the cost
0.6*80=48

the answer is b.)

< 1=< 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
