Answer:

The numbers are 1652.5 and 1647.5

Explanation:

We are told that there are two numbers, let's call them a and b, and that "One number is five more than (the other)". We can express this like so:

a = b + 5

We're also told that "The product of the numbers is 3300". Which can be expressed as:

a + b = 3300

To solve this, we can simply replace "a" in the second equation with it's value given in the first equation, "b + 5". This gives us:

a + b = 3300

(b + 5) + b = 3300

2b + 5 = 3300

2b = 3300 - 5

2b = 3295

b = 1647.5

Now we can take that value of b and plug it back into one of our first equations to solve for a:

a = b + 5

a = 1647.5 + 5

a = 1652.5

Now let's test our results by plugging them into the other equation:

a + b = 3300

1652.5 + 1647.5 = 3300

3300 = 3300

So that checks out, and the numbers we want are 1652.5 and 1647.5
