Eduardo spent 35% of his time at the theme park on roller coasters. if he was there for 8 hours, how much time did he spend on roller coasters?

2.8 hours (equivalent to 2 hrs, 48 min)

Work Shown:

Multiply 0.35 by 8 and you'll get 2.8, which breaks down as follows

2.8 hrs = (2 hrs) + (0.8 hrs)

2.8 hrs = (2 hrs) + (0.8 hrs)*(60 min/1 hr)

2.8 hrs = (2 hrs) + (0.8*60 min)

2.8 hrs = (2 hrs) + (48 min)

2.8 hrs = 2 hrs, 48 min

pls ask

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
