Nina wants to buy a bicycle thats costs $150. she has saved 6 percent of the total cost of the bicycle. how much money has nina saved? show your work. what percent of the total cost does nina still have to save?

The understanding one needs to work with percentages is:
1/100 = 1% = 0.01
Also
6/100 = 6% = 0.06
also
25/100=1/4=0.25=25%

To find a spesific share of a total, we can multiply the perectage with the total, like this: Total * 6% or in a way easier to work with: Total * 0.06 or (Total * 6)/100

If you have a calculator i would recommend using the decimals, as they are one of the easiest to type in - and remember once you get the hang of it.

To find the money Nina has saved, you do the following.
150*0.06=9$
Nina has saved 9 dollars.

The remaining percent she needs, is
100-6=94%

She still needs money for 94% of the bike.
