For this case, the first thing we must do is define variables.
We have then:
n: number of journals.
We now write the equation for the profits.
We have then:
P (n) = (6-1.50) n - 600
Rewriting:
P (n) = 4.50n - 600
Answer:
An equation that represents the profit function of the newsstand is:
P (n) = 4.50n - 600
Step-by-step explanation:
sould we need percentage or on the total number of people
The answer is 3 + c
3 coins are 3
c coins are c
Their sum is 3 + c
Its C because you multiply 10 with 1 and 9x
