We know that he weeds gardens for 15 hours, and mows lawns for x hours.
If he wants to earn $252 per month, we can express the following

Now, we solve for x

<h2>Hence, he has to mow lawns for 13 hours to earn at least $252.</h2>
14612 is the answer to your math problem. This is so easy. just use a calculator.
The percentage rate of increase is 36.2% and the exponential function represent the growth.
<h3>What is an exponential function?</h3>
It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent 
where 'a' is a constant and a>1
We have exponential function:

If we compare with

If 1+r > 1
1.362 > 1
So the growth rate r is
1 + r = 1.362
r = 0.362
r = 0.362×100
r = 36.2%
Thus, the percentage rate of increase is 36.2% and the exponential function represent the growth.

20% = 20/100 = 1/5
1/5 of 3500
1/5 X 3500/1 = 3500/5
3500/5 = 700.
Answer:
Largest prime factor of the given expression is <em>379.</em>
Step-by-step explanation:
Given the expression:

To find:
The largest prime factor of the given expression.
Solution:
First of all, let us factorize the given expression.

Let us learn two formula:


Applying the above formula in the expression written above:
...... (1)
Similarly:
........ (2)
Multiplying the expressions from (1) and (2) to get the result:

So, largest prime factor of the given expression is <em>379.</em>
