(i) Maximum number of students : 32

Watched TV for (4−5) hours

(ii) Students who watched TV for less than 4 hours belong to category : 1−2hrs,2−3hrs or 3−4hrs.

=34

Total number of students: 8+6=14

Step-by-step explanation:

hope it helps you :)

for b its (t) and c its (d)

step-by-step explanation:

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
