Percy used to have 100% of the shirts (before he started selling them). Since then, he has given away 90% of the shirts and is now left with only 10% of what he used to have. He currently has 25 shirts, meaning that 25 is 10% of what he had.
Lets set up a proportion:
25 shirts : 10%
x shirts : 100%
x = 25*100 / 10
x = 2500 / 10
x = 250 shirts
Percy started off with 250 shirts.
Answer:
$300
Step-by-step explanation:
1/4of $1800=$450-$150=$300
Answer:
Subtract 1/2 from both sides of the equation.
w=1/4w+1 1/2
Multiply both sides by 4
4w=w+6
Subtract w from both sides
3w=6
Divide both sides by 3
w=2
Check answer
2+1/2=1/4(2)+2
2 1/2=2 1/2

Answer:
{1,3,4,5,6,7}
Step-by-step explanation:
Here , U represents the universal set
L’ = {2,4,6}
L’ is what we have in the universal set but not present in set L
(m n L’)
This is the set that contains the elements that are present in both set ONLY
So this is;
{2}
(M n L’)’ = {1,3,4,5,6,7}
N’ = {1,7}
So the union of both would be;
= {1,3,4,5,6,7}
