Including the bus driver, there are 12 people on a bus. during the ride, each person produces 725 btus (british thermal units). the interior of the bus measures 39 feet by 7.25 feet by 6.5 feet. how many btus per cubic foot are produced? rounded to the nearest hundredth.

(total number of BTUs) / (total number of cubic feet)

= (725 * 12   BTUs) / (39 * 7.25 * 6.5   ft3)

= 8700 BTUs / 1837.875 ft3

≈ 4.73  BTUs / ft3

step-by-step explanation:

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
