Hello! Your answer is B) 105.
Our problem tells us that we have 70 and we have to increase it by 35. This means we have to add 35 to 70 for it to increase. This would look like this:
70+35=?
Using mental math or a calculator it is verified that 70+35=105.
We can also eliminate the other answer choices since they have a .5 at the end of them, and since neither 70 or 35 in our equation have numbers in the decimal place, the answer won't either, so that way we can be sure the other answers are wrong!
Please consider giving the brainliest answer and a thanks to the answers you find most helpful! :)
Edit: Asker meant to ask about what a 35% increase would be to 70. Turn the percentage into .35 and multiply by 70. This is 24.5, now add to the original 70 and the answer is 94.5!
