A television and DVD player cost a total of $1272. The cost of the television is two times the cost of the DVD player. Find the cost of each item. Cost of television: Cost of DVD player:

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
