Paulo earns a salary of 15000$ per month for selling cell phones. He receives an extra 30$ for each cell phone over 100 units that he sells. How much will be make if he sells R cell phones? 50 cell phones?

check = 15,000 if R</= 100

check = 15,000 + 30 (R-100) if R>100

since 50<100, he gets 15,000

To determine how much Paulo will make if he sells a certain number of cell phones, we can use the given information.

First, let's calculate the additional amount Paulo will receive for selling cell phones above 100 units. He receives $30 for each cell phone over 100 units. Thus, for R cell phones, Paulo will earn $(R-100)*30.

Next, let's calculate Paulo's base salary for selling 100 cell phones. Since he earns $15,000 per month, which is his base salary, we can conclude that he receives this amount for selling 100 cell phones.

Now, let's add the additional amount he earns for selling over 100 cell phones to his base salary. We can calculate this by adding $(R-100)*30 to his base salary of $15,000.

Therefore, to find out how much Paulo will make if he sells R cell phones, we can use the formula:

Total earnings = Base salary + Additional earnings
Total earnings = $15,000 + $(R-100)*30

If R = 50 cell phones, we can substitute R with 50 in the formula to find out how much Paulo will make:

Total earnings = $15,000 + $(50-100)*30
Total earnings = $15,000 + $(-50)*30
Total earnings = $15,000 + $(-1,500)
Total earnings = $13,500

So, if Paulo sells 50 cell phones, he will make $13,500.
