Answer:
1) 26.1% increase
2) 20% decrease
Work:
1)
-subtract the larger # from the smaller # to figure out what the change was.
[tex]8.8 - 6.5 = 2.3[/tex]
-divide 2.3 by the orriginal ammount (8.8) to find your answer as a decimal
[tex]2.3 \div 8.8 = 0.261[/tex]
-take 0.261 and multiply it by 100 to have your answer as a percent
[tex]0.2614 \times 100 = 26.1[/tex]
-if the original number increased than it is percent increase and if the original number decreased than it is percent decrease
2)
-subtract the larger # from the smaller # to figure out what the change was.
[tex]15 - 12 = 3[/tex]
-divide 2.3 by the orriginal ammount (15) to find your answer as a decimal
[tex]3 \div 15 = 0.2[/tex]
-take 0.2 and multiply it by 100 to have your answer as a percent
[tex]0.2 \times 100 = 20[/tex]
-if the original number increased than it is percent increase and if the original number decreased than it is percent decrease
