while \[.07=7\%\] that just means 7 cents is 7 percent of a dollar

Answer 34

\(percent~change = \dfrac{new~number - old~number}{old~number } \times 100\)

Answer 35

That's what bI did mathstudent that is what I showed them

Answer 36

I did that

Answer 37

ok u know what i think misty is right, sorry danieke i messed up

Answer 38

People people. I am actually correct. Because of the fact that I actually did this problem and got it correct.

Answer 39

\(percent~change = \dfrac{2.89 - 2.82}{2.82} \times 100 = 2.5\%\)

Answer 40

actually

Answer 41

you know what lets just give mathstudent the medal

Answer 42

Since the percent change is positive, it is a percent increase.

Answer 43

the answer is 2.5 i did the math wrong i did 2.83

Answer 44

instead of 2.82

Answer 45

and i totally did the math wrong

Answer 46

You can memorize the formula for percent change, but it's important to understand it.
The first step is to subtract the original price from the new price.
That gives you the change.
In this case, 2.89 - 2.82 = 0.07
The change in price was $0.07

Answer 48

THE FINAL ANSWER IS.

Answer 49

THE PERCENT INCREASE IS 2.5% PERCENT

Answer 50

actually 4 are viewing

Answer 51

Now we want to know what percent of the original price is the change.
0.07 is what percent of 2.82?
To find that, we divide the change by the ORIGINAL price, and multiply by 100.
\(\dfrac{0.07}{2.82} \times 100 = 2.482...\%\)

Since the problem asks to round to the nearest tenth of a percent, the answer is 2.5%
