Cheese sticks that were previously priced at "5 for $1" are now "4 for $1" Find the percent decrease in the number of cheese sticks you can buy for $1? HELP!
Well how much less can you buy now than you could buy before?
What do you mean?
SOMEONE help me!
Before you could buy 5 right? And now you can only buy 4? so how many less is that? ( I know it's obvious but it's important to the problem)
oh, it's 1!
^^
Yeah So you could buy 5 before right? So if you can buy 1 less, out of 5 TOTAL what is your percentage?
20%!?!?!
I'm not sure?
Yep
Good job :)
oh, THANK YOU!
And what's the percent increase in the price per cheese stick?
Someone help!
Oh sorry didn't see this Well calculate the base rates of the cheesesticks How much did 1 cheesestick cost before and how much does 1 cost now?
I think 0.20 cents?
yes
now find the new price
And the 4 for $1 is 0.25
next find the increase in price (change in price)
0.05 but i need to put it in percentage
yes, now we use the idea that percent increase (or decrease) is the fraction amount of change/original amount in other words, 5/20 change that to a decimal
0.4 =40%
5/20 is not .4
you could simplify 5/20 by dividing top and bottom by 5 to get ¼
oh, 25%
now divide 4 into 1.0 (or use a calculator.. though it would be good to be able to do it by hand) yes you get 0.25 then the last step is change the decimal to a fraction by 1) multiply by 100 2) append a % sign you get 25%
The price increased by 25%
ok, thank you soooo much! |dw:1454025443409:dw|
