Answer:
$2.90
Step-by-step explanation:
The quantity of the 1st type of candy be x lb and that of the second type − y lb with the price of $ p/lb.
Then, x=5y/12 or y=2.4x.
The "total price" equation will be: 4.6x + 2.4xp = 3.4(x+2.4x).
Solving for p, we get p = $2.90.
Yes, the equation given above is proportional. The variables y and x are directly proportional to each other. <span>Two variables are proportional if a change in one is always accompanied by a change in the other, and if the changes are always related by use of a constant multiplier.</span>
The understanding one needs to work with percentages is:
1/100 = 1% = 0.01
Also
6/100 = 6% = 0.06
also
25/100=1/4=0.25=25%
To find a spesific share of a total, we can multiply the perectage with the total, like this: Total * 6% or in a way easier to work with: Total * 0.06 or (Total * 6)/100
If you have a calculator i would recommend using the decimals, as they are one of the easiest to type in - and remember once you get the hang of it.
To find the money Nina has saved, you do the following.
150*0.06=9$
Nina has saved 9 dollars.
The remaining percent she needs, is
100-6=94%
She still needs money for 94% of the bike.
Answer:
2/1 or 2
Step-by-step explanation:
the way to find the slope is rise over run, if you count the units you see that for every time it rises 2 it runs 1, then divide.
