Answer:

22

Step-by-step explanation:

Solve the inequality  (20 + 0.5x) + 0.15(20 + 0.5x)   ≤ $62.10 for x:

20 + .5x + 3 + 0.75x ≤ 62.10

Combining the x terms, we get:

20 + 3 + 1.25x ≤ 62.10.

Combining the constants on the left:

23 + 1.75x ≤ 62.10

Combining the constants:

1.75x = 39.10

Solving for x:  39.10/1.75 = 22.34

Thus, the max number of whole pages she can have in her book is 22.

Answer:

Option C. -3x^2-13x-5

Step-by-step explanation:

we know that

To find how much greater is the area of room A than the area of room B. subtract the area of room B from the area of room A

so

(5x^{2}-7x-6)-(8x^{2}+6x-1)\\ \\= (5x^{2}-7x-6)-8x^{2}-6x+1\\ \\=(5x^{2}-8x^{2})+(-7x-6x)+(-6+1)\\ \\=-3x^{2} -13x-5
