Answer:
0 ≤ c ≤ 12
Step-by-step explanation:
The function can be rearranged to ...
p = 200c(12 -c) -4700
suggesting that revenue will be zero for a charge of 0 or for a charge of 12, and that fixed expenses are 4700. Charges less than 0 are uninteresting, and charges high enough to cause the number of customers to be negative also don't make any sense in this context.
Though out of the range of likely consideration, charges low or high enough to cause profit to be negative (more than 9.54, for example) seemingly can be reasonably modeled by this function.
<span>let's say, you have 2(x+5)=10
What you do is multiply the x and the 5 by 2 so it now looks like
2x+10=10
The act of multiplying the inside numbers by the number outside the parenthesis is the distributive property. Now using distributive property to remove grouping symbols is similar
</span>Lets say you have 18 + {2 + 3 (6 -1*2)} first you would multiply 2by1
= 18 + {2 + 3(6 - 2)} then subrtact 2 from 6
= 18 + {2 + 3(4)} then multiply 3by 4 take away () grouping signal
= 18 + {2 + 12} then add 2 and 12
= 18 + {14} then take away the last grouping signals
= 18 + 14 then add 18 and 14
= 32
B: -5x + 5y - 5
Hope this is the answer you're looking for (:
