Answer:
A = 800, B = 200, C = 400 Andy D = 400
Step-by-step explanation:
8 < x < 22
If x is the third side , then
difference of 2 sides < x < sum of 2 sides , that is
15 - 7 < x < 15 + 7
x+y ≤ 20
7.50x+6y ≥ 92
x = dog walking in hours
y = car washing in hours
Since the remander is 0 the answer is 2x²+5x+2
