Answer:
2(c-1)
Step-by-step explanation:
MIke is c
Steve is 2c
Steve was 2c -2 two years ago
Answer:
a) C(x) = 4x + 350
b) 13x; $13
c) 39
Step-by-step explanation:
a) Initial cost of lawnmower = $350
Maintenance cost for 1 lawn = $4
Maintenance cost for x lawns = 4x
Total cost function, C(x) = 4x + 350
b) Revenue = Cost + Profit
= C(x) + P(x)
= 4x + 350 + 9x - 350
= 13x
Charge per lawn = 
= 
c) For Jimmy to make a profit, P(x) must be greater than zero i.e.



The smallest integer value of x that satisfies this inequality is 39. Therefore, Jimmy needs to mow 39 lawns in order to start making profit.
Ok so ummmm idk how to speck in that but well ummmmm idk
