Answer:
The complete question is
Find the percent of change. Round to the nearest tenth if necessary.
25 points to 50 points
.
Notice that this change is an increase, to fint the percetange of change, we just need to divide and then multiply by 100 to have it in percetange expression:
[tex]\frac{50}{25} \times 100=2 \times 100 = 200\%[/tex]
So, the percentage of change is 100%, because the change is 25, that was the increase.
125 invitations to 75 invitations
.
[tex]\frac{75}{125} \times 100 = 60\%[/tex]
Which means 75 invitations represents 60% of the old number of invitations.
So, the percentage of change is 40%, because that's the percentage of the difference.
32 pages to 28 pages
.
You can do another process, first find the difference:
[tex]32-28=4[/tex]
Then, you divide:
[tex]\frac{4}{32} \times 100= 12.5 \%[/tex]
So, the percentage of change is 12.5%.
7 players to 10 players.
[tex]10-7=3\\\frac{3}{7} \times 100=0.43 = 43\%[/tex]
So, the percentage of change is around 43%.
