Question

tell whether each percent change is an increase or decrease. Then find the percent change. Round to the nearest percent. original amount: 45 new amount: 60

Answer 1

What do you think about this question? Any ideas?

Answer 2

None. My teacher hasn't taught me this yet. I know it's an increase though.

Answer 3

\[\%\Delta = \frac{|a - b|}{a} \times 100\]

\(\%\Delta = \) Percent Change
\(a = \) Old Amount
\(b = \) New amount

Answer 4

Ook Can u use the actual numbers in that ?

Answer 5

Yes, that's what you're supposed to do. In this case:
\(a = 45\)
\(b = 60\)

Answer 6

Thank u. It's hard for me to understand this stuff. ok so it would be

x = 45−60
==== ×100
45
45 - 60 = -15
15
== = 3
45
3(100) = 300

Answer 7

\[\frac{15}{45} = \frac{1}{3}\]

Answer 8

ok
so 1/3(100) = 33

Answer 9

Correct.

Answer 10
