So Blakes sleep 8 hours per night during the school day
8 hours/night...................................100%
6.5 hours/night...................................?
6.5*100/8=81.25
the change in percentage is 100-81.25=18.75%
the percentage change is 18.75
if it is easier for you, another method is:
8-6.5=1.5 subtract the original amount to the new amount
1.5/8=0.1875 divide by the original amount
0.1875*100=18.75 find the percentage
Hey there!
If the price per orange is $.26 and we want to know how many oranges he bought and we have our total, we can set o equal to how many oranges he got and set up an algebraic equation:
0.26o = 2.08
We multiply .26 by o because o is how many oranges he bought and that's what we're solving for- so we multiply by the unit price.
To isolate o, we divide both sides by .26 to get:
The answer is C- Jim bought 8 oranges.
Hope this helps!
