This kind of problems requires to add the working velocities. The total velocity is the sum of the individual velocities.
Anita's velocity = 1 pool/8 hours
Chao's velocity = 1 pool/6 hours
Combined velocity 1/8 + 1/6 = (3 + 4)/24 = 7/24 pool/hour
Time = 1 pool / (7/24) pool/hour = 24/7 hour =3.43 hours
Answer:
y intercept is -10
x intercept is 3
the number at which the line intersects with the line is what it will be. Remember that the x intercept is horizontal and the y intercept is vertical
You can each order from: Column A- 6 times, Column B- 4 times
