A+J=36

2A-3+A=36
A=13
J=2A-3=23

To find out how many sales John made, we first need to calculate Ana's sales total.

Let's assume Ana's sales total as "x".

According to the given information, John's sales total is three less than twice Ana's sales total. Therefore, John's sales total can be calculated as 2x - 3.

The total sales for the day is given as 36. So, we can write the equation as:

x + (2x - 3) = 36

Now, let's solve the equation to find the value of x (Ana's sales total):

3x - 3 = 36
3x = 36 + 3
3x = 39
x = 39 / 3
x = 13

So, Ana's sales total is 13.

Now, let's find John's sales total:

John's sales total = 2x - 3
John's sales total = 2(13) - 3
John's sales total = 26 - 3
John's sales total = 23

Therefore, John sold 23 items.
