I'm pretty sure it would be $19. You can check my work to make sure.

First, I multiplied 15 by 20%, which in decimal form would be .20 or .2. I got the answer 4.00, which could also be simplified to 4. Afterwards I added 4 to 15 to add the profit the market gets when they have to pay back the $15 for pound. 4+15=19, so $19 for 20%.

**Answer:**

6*5=30cm (Height of tomato plant)

**Step-by-step explanation:**

bean plant is 6 centimeters tall

tomato plant is 5 times as tall as his bean plant

6*5=30cm

3)

f(x) =(x+1)/4

so

f(6a) = (6a+1) / 4

f(6a) =3/2(a) + 1/4

8)

f(x) =(x+1)/4 = 0

x + 1 =0

x = -1

answer

x = -1 makes f(x) = 0

9)

(x+1)/4 >= 10

x + 1 >= 40

x >= 39

Answer
