(Change)/(original) *100
.05/2.87 *100
1.7%
We know that the final price after a discount of 20% is $12,590. If the original price was x, the price after discount is 80%<span> of x (</span>100%<span> - 20%). OP (original price) multiplied by (1-20/100) equals $15,737.5
I hope this helps.</span>
Answer: red is 13.36
Blue is 93.625
Step-by-step explanation:
Let the red marbles be y
Based on the question,red is 4times which means 4y
And blue is 7times greater than red which means 7(4y)
Blue + red=107
7(4y) + 4y=107
28y+4y=107
32y=107
Divide both sides by 32
Y=3.34
Red =4y
Red= 4(3.34)
Red =13.36
Blue= 7(4y)
Blue=7(4×3.34)
Blue= 93.625
Well it says 1 cup of sugar (S) for every 20 cookis (N) is like saying the amount of cookies(N) is increased by a factor of 20 times the cups of sugar (S) used. which can be written:
cookies(N) = 20 * cups sugar (S)
So you just get rid of the words and use the variables S and N and get
N = 20S
that is the equation. to graph it just plug in a few numbers for s and get the n. It's just like x and y but where x is S and y is N
I remember doing this in 5th grade, maybe 6th.
