Thomas started a lawn-mowing business in florida, in which he has x lawns on his route. his costs are $6 per lawn for fertilizer and $14 per lawn for labor. a) if he charges $25 per lawn, write a polynomial that represents his weekly profit. b) if thomas mows 40 lawns in a week, what is his weekly profit? c) if thomas mows 40 lawns per week, what is his annual profit?

Number of lawn mowing = x.

His cost per lawn for fertilizer = $6.

His cost per lawn for labor = $14.

Total cost per lawn for fertilizer and  per lawn for labor for him = 6+14 = $20.

He charges = $25 per lawn.

So, profit per lawn = 25 - 20 = $5.

Therefore, for mowing x number lawn could be represented by polynomial that represents his weekly profit.

b) For mowing 40 lawns per week total profit would be

P(40) = 5(40) = $200.

c) Number of weeks an year = 52.

Therefore,

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
