So 20% is 1/5 as a percent.
So 1/5 multiplied by 5 equals 5/5, or 1.
So if 1/5 = 6, then 6 multiplied by 5, or 30, must equal 5/5, or 1.
So the total number of dolls in Amyia's doll collection is 30.

Answer: 28% discount</h3>
==========================================
Proof:
1250 - 900 = 350 is the amount saved
350/1250 = 0.28 = 28% is the discount
----------
You take 28% of 1250 to get 350, then subtract off 350 to end up with 900
1250 - (28% of 1250) = 1250 - 0.28*1250 = 1250 - 350 = 900
---------
Or a shortcut is
1250*(1-0.28) = 1250*0.72 = 900
This is because the price is reduced by 28%, so you still pay the remaining 72%
Answer:
a) 3(x+2)
b) 13y+12
Step-by-step explanation:
3x+6 divide by six and put the rest in parenthesis 3x/3=x 6/3=2
3(x+2)
13+14y-1-y
rearrange so like terms are next to each other
13-1+14y-y
combine like terms
12+13y
