Sati [7]

4(2n - 9) = 10n - 8

8n - 36 = 10n - 8

8n - 8n - 36 = 10n - 8n - 8

-36 = 2n - 8

-36 + 8 = 2n - 8 + 8

-28 = 2n

-28/2 = 2n/2

wlad13 [49]

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.
