$54 (if 10 for each of the 3 students and 4 dollars each of the 6 students)
$14 if not
Answer:
The solutions are -1 and 2/5
Explanation:
The general form of the quadratic equation is:
ax² + bx + c = 0
The given equation is:
5x² + 3x - 2 = 0
By comparison:
a = 5
b = 3
c = -2
Now, to get the roots (solutions) of the equation, we will need to use the quadratic formula shown in the attached image
Substituting in the equation, we would find that:
either x = -1
or x = 2/5
Hope this helps :)

You have to first find out the ratio of the different plants
Tomato:Pepper:Squash: Pumpkin: Total
= 88:44:33:66:231
Divide 231 by 77 =3
This means that the original number of plant is also 3 times of 22, as the ratio and proportion of this plant out of the total number of plant will be the same.
Hence you multiply 22 with 3 to get 66, which is the original number of pumpkin plants.
