Answer:
21.62% more
Step-by-step explanation:
20 mins * 3 = 60 mins (1 hour)
10 baskets * 3 = 30 baskets
3$ * 30 baskets = 90$
90$ - 74$ = 16$
74 / 100 - 0.74
90 / 0.74 = 121.62
So she makes 21.62% more with 3$ per basket.
Answer:
Step-by-step explanation:
If the new fraction is 8/12 I will show how to find it.
Let's say the original denominator is x, then the numerator is x-4, so we have (x-4)/x.
Then it says f we add 4 to both, so now we have x/(x+4) this equals 8/12. Now, keep in mind -4 cannot be an answer because it would make x/(x+4) be divided by 0 which wouldn't exist.
Now we just use algebra.
x/(x+4) = 8/12
12x = 8(x+4)
12x = 8x + 32
4x = 32
x = 8
So the original fraction (x-4)/x = (8-4)/8 = 4/8
