C7 D 8

Can someone explain this plz i have an hw and I don’t understand this PLZ HELP

Step-by-step explanation:

70x < 350

x < 5 (divide both sides by 70)

The number of tablet computers must be strictly below 5.

Hence the next integer below 5 is 4. (A)

The area of the room = (40 x 24) - (20 x 12)

Area = 960 - 240 = 720 square feet

Divide square feet by width of a strip:

720 / 12 = 60 linear feet.

The answer is D.
