Question 32015
Hello!
The profits can be calculated as (Revenue - Costs).

Let's call X to the number of toys he sells. If he sells each for $3.00, the his revenue is:

{{{Revenue = 3X}}}

Since the cost of each is $1.80, then the total cost is:

{{{Cost = 1.8X}}}

Therefore, his profits, as a function of X, are:

{{{Profits = 3X - 1.8X = 1.2X}}}

So now we set the profit equal to 36 and solve for X:

{{{1.2X = 36}}}
{{{X = 36/1.2}}}
{{{X = 30}}}

He must sell 30 toys in order to make $36.00 in profits.


I hope this helps!
