Seven more than 3 times a number is equal to 49 can be put into an equation form, which would be 7 + 3x = 49. With this equation we can work it out, first we will subtract 7 from both sides of the equation to cancel out the 7. 49 - 7 = 42. Now we have 3x = 42. To isolate x and give us the answer we will divide by 3 on both sides, since 3 is being multiplied by x. This will give us our answer, which is 14.
From the calculations, we can see that the number of beetles after three years is 11618 beetles.

What is an exponential problem?</h3>
The term "exponential problem" has to do with any problem in which the increase or decrease occurs exponentially.
In this case we have P = Poe^rt
Po = 10,000
r = 0.05
t = 3
P = 10,000 e^(0.05 * 3)
P= 11618 beetles
