Main Street Gym is more expensive. I just answered this same question.
Total jellybeans pulled out: 15 + 20 + 12 + 8 = 55
Proportion of yellow jellybeans: 20 / 55 = 4/11
(4/11) * 22 = 8.
Answer: 8
(4, ?) is on 8x - 3y = -10
The ? is the missing y coordinate. (4, y) satisfies 8x - 3y = -10
8x - 3y = -10. From point (4, y), we would replace x = 4 in the equation below. y remains the unknown.
8*4 - 3y = -10
32 - 3y = -10
-3y = -10 - 32
-3y = - 42
y = -42/-3
y = 14
So the coordinate is (4, 14)
