Question

Anyone knows the answer to these questions?

Answer 1

So take the given value for question one, 210, and realize that it increases by 10%. What is 10% of 210? If you don't know, basically 10% = 0.1 so multiply 210 by .1 and add that to 210. leave a comment if you can't figure it the answer to either of them and I'll help more.

Answer 2

The answer to a. is $231 and b. is $52.80, how I got my answer.

I found 10% of 210 which is 21, so I added !210+21=231, and I found 10% of 48 which is 4.8, so I added 48+4.8=52.80.

I hope this helps!
