Sophie put up three bookshelves in her room. The top shelf is 3.88 feet long, the
middle shelf is 2.63 feet long, and the
bottom shelf is 4.56 feet long.

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

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
