Explanation / Answer

7) Here is no figure 1.

8) Given equation : L = 0.25t + 57

Here, option B is the correct answer.

9) The result of increasing x by 40% is x+0.4x

10) The required equation is : M = 100+20m

11) By condition C = R

i.e., 40*T + 1200 = 3000

i.e., 40*T = 3000 - 1200

i.e., 40*T = 1800

i.e., T = 1800/40

i.e., T = 45

Therefore, 45 tables must be sold in order to break even.
