circle the expression(s) equivalent to 42 divided by the sum of 2/3 and 3/4 (2/3+3/4) divided by 42 (42 divided by 2/3) + 3/4 42 divided by (2/3+3/4) 42/ 2/3+3/4

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

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
