Answer:
36 x 144 = 4104
Step-by-step explanation:
Using linear functions, we have that:
A.
For Company A: 
For Company B: 
B. The salaries will be the same after 7 years.
A linear function is given by:
In which:
- m is the slope, which is the rate of change.
- b is the y-intercept, which is the initial value.
Item a:
- For Company A, the salary starts at $31,000, with a raise of $3,000 each year. Thus,
, and the salary after n years is given by:
- For Company B, the salary starts at $38,000, with a raise of $2,000 each year. Thus,
, and the salary after n years is given by:
Item b:
- They will be the same after n years, for which:
Then
The salaries will be the same after 7 years.

Answer: 15 gallons
Step-by-step explanation:
There is 100% in any full thing. When the water tank was full, it had 20 gallons. After 25% of the water was removed, there is 75% left (100% - 25% = 75%). 75% can also equal 0.75. 20 × 0.75 = 15 gallons.
Answer:
(a) 412 +A -B
(b) 412 +A -B + (A-20) -(B+14)
(c) 378 +2A -2B
Step-by-step explanation:
Water flowing in adds to the amount in the reservoir. Water flowing out subtracts from the amount in the reservoir.
__
(a) 412 + A - B . . . . at the end of January
__
(b) Flowing in was (A -20), flowing out was (B +14). In February, we start with the amount at the end of January.
(412 +A -B) +(A-20) -(B +14)
__
(c) Simplifying the above, we have ...
412 -20 -14 +2A -2B = 378 +2A -2B
So 60 + 20 is 80, and that is $80 a mile. 80 x 3 = 240, + 80 = 320. and then we could say 2/6 of 80 is about 28, right? so i suppose 4 2/6? sorry if it's wrong, just trying to help to the best of my ability
