Mindy's dog, Rex, weighed 80 pounds a year ago. Now he weighs 92 pounds. What is the percent increase in his weight?
The options are A. 13% B. 16% C. 12% D. 15%
Okay to find increase subtract the new number by the original 92-80=
which is 18 right
Not quite
Oh my Jesus i hate when i try to do things in meh head ... my head is crazy
OK it is 12
Yes
K
To find the percent change, set that number over the original \(\frac{12}{80}\)
next?
Divide them
so \[12/80\]
0.15?????
Yes
Now multiply it by 100
so is hat yhe answer
that the*
15% i mean
Yes
Okay
Leo weighs 10 pounds of dog food at the pet store. The scale mistakenly lists the bag at 11.5 pounds. what percent difference Candice buys a board that is 12 feet long. The store incorrectly measures and prices the board at 13.2 feet. what percent difference Lenny's bug collection has a bug that is 16 centimeters long. Lenny fumbles with a ruler and incorrectly reports the bug to be 18 centimeters long. Josie's GPS shows that she traveled 20 miles in her car. Her car's odometer is slightly off and measures the distance as 24 miles.
Okay then the general idea for these is to do the highest number minus the lowest Then set what you got from that by the first (original/small) number and multiply by 100
11.5-10=1.5 1.5*100=150 that is the first one 13.2-12=1.2 1.2*100=120 18-16=2 2*100=200? 24-20=4 4*100=200?
Oh no I did it wrong didnt i
Yeah you were supposed to set the difference over the original number So for the first one it would be 1.5/10 and then multiplied by 100
1.5/10=0.15
Right and then multiply by 100
0.15*100?=15
so 15%?
Yes it is 15%
okay
so... next is...?
`13.2-12=1.2 1.2*100=120` you want to set 1.2 over the original amount
?so 1.2/12?
Yes
=0.1
so the answer is 10%?
Yep
next
pls*
18-16=2 2*100=200 2 over the original amount
2/16 or 18?
wait i hink i know the answer
think*
20%?
It is 2/16 which is 12.5 or 12.5% xD
oh
:P
thx i made 100%
Nice
