Answer:
12
Step-by-step explanation:
Let the total number of donuts in the pack be x.
Amy = 2/3x
Anna = 1/4x
David = 1
x - 2/3x - 1/4x = 1
Find common denominators for 2/3 and 1/4
The common denominator is 12
2/3 * 4/4 = 8/12
1/4 * 3/3 = 3/12
x - 8/12x - 3/12x = 1
x - 11/12x = 1
1/12x = 1
x = 12
You can always check
Amy = 8
Anna = 3
So David must equal to 1
Hope this helps :)
Have an awesome day!
X and y vary directily means
y=kx
72=3k
divide both sides by 3
24=k
k=24
y=72

Hi!
To answer this, first we have to find how much 1 notebook costs. We can do this by dividing:
Cost/amount = ?
Or in this case
5.25/5 = 1.5
Now we have to find how much 3 notebooks cost. We can do this by multiplying:
Cost of one x amount = ?
Or in this case
1.5 x 3 = 3.15
The answer is 3.15
Hope this helps! :)
