Answer:
The correct answer is A) $105
Step-by-step explanation:
In this real-world problem, the cost to groom both dogs is (the puppy) + (the adult dog) = x.
For the first step, y = 40, if x <= 25.
y = 50, if 25 < x < 50.
if x >= 50, then y = 0.50x + 25
So therefore, substitute the puppy + adult dog = x
25 + 80 = x
105 = x
So, the final answer is $105.

Answer:
Step-by-step explanation:
-2(4-3x)+(5x-2)
-8+6x+5x-2
11x-10
1 mile at 12 m/h is .2 m/min
1 mile at .2 m/min (1/.2) = 5 min So the first mile took 5 minutes
To find how fast the second mile was:
You know it was 1 mile and it took 10 minutes
1/10=.1 m/min which is 6 m/h
The average speed is 6+12/2=9 m/h
