Tina's salary was $20,350 last year. This year she is getting paid $2,000 more. What was the percent increase to the nearest percent? Show me how to do it please not just answer

OpenStudy (imer):

What you think is the fist step?

OpenStudy (anonymous):

Idk Thats Why Im Asking You Guys

OpenStudy (imer):

A person always have a guess but that guess some times does not lead to the answer. I just wanted to know your guess. Anyways, Lets start with an easy example, Let say you are paid $2 dollar in a hour but next hour you are paid $1 more, what is the percentage increase?

OpenStudy (anonymous):

!% Increase

OpenStudy (imer):

!% ?

OpenStudy (anonymous):

1 Sorry Had Shift On

OpenStudy (imer):

1% is incorrect, tell me what is half of 2?

OpenStudy (anonymous):

1

OpenStudy (imer):

but I can say "1" is 50% of "2" right?

OpenStudy (anonymous):

Yea

OpenStudy (imer):

So if I pay you 2 dollar per hour, next hour you are paid $1 more, whats the increase?

OpenStudy (anonymous):

50%

OpenStudy (imer):

Correct, so you are getting 50% more of the original amount which was $2, therefore the increase is 50%. Now apply the concept to the question you posted.

OpenStudy (imer):

We know "1" is half of "2" which I can write as \[\frac{ 1 }{ 2 }\]and if I multiply by "100", I converted half in to percentage. \[\frac{ 1 }{ 2 }*100=50\]

OpenStudy (imer):

Can you tell me how we will solve the original question using the concept I showed?

OpenStudy (triciaal):

percent means per 100 set up a ratio increase : original is the same as x:100 where x is the percentage; the amount out of 100 for this problem the increase is 2000 and the original is 20350 |dw:1403658266899:dw|
