Multiply 200 by .15, since 15% is .15 as a decimal. 200 x .15 = 30. This means that his health care rate will increase by $30 next year.
Answer:
c
Step-by-step explanation:
Step-by-step explanation:
Distance = rate × time
If B is the rate of the boat, and C is the rate of the current, then we can write two equations:
18 = (B + C) × 3
18 = (B − C) × 9
Simplifying the equations:
6 = B + C
2 = B − C
Add the equations together to eliminate C:
8 = 2B
B = 4
Plug into either equation to find C:
C = 2
The boat's rate is 4 mph, and the current's rate is 2 mph.
Answer:
60
Step-by-step explanation:
K is the constant of proportionality or unit rate
(x, y)
(0, 0)
(2, 120)
(3, 180)
(4, 240)
120/2=60
180/2=60
240/2=60
The constant of proportionality or unit rate is 60
