Answer:
d
Step-by-step explanation:
527 / 17 = 31
The equation for Cole's earnings per hour is
y = 12.5 + 0.75x
for Amad's:
y = 10.50 + 2x/2
When we equate them
12.5 + 0.75x = 10.50 + 2x/2
Solving for x
x = 2
They will have the same earning rate after 2 years
4 sticks and 2 brushes
(10.5*4)*(24*2)=90
Unit rate = 20/4 = 5 m/s
hope it helps
