Answer:
shirt= $8
cap=$3
Step-by-step explanation:
rearrange one of the equations
y=11-x
then plug into the other equation
2x+3(11-x)=25
solve
2x+33-3x=25
-x+33=25
subtract 33 from both sides
-x=-8
divide by -1
x=8
the put that answer into original equation
8+y=11
subtract 8 from both sides
y=3
At first they bought 40 uniforms for $3,000. When divided, the result came out as 75$ per each uniform. If they only received 40$ back then, 70-40=30. So the difference was 30$ per uniform.
Right now, the ratio of nonfiction to fiction is 9:18. If this is reduced, it is a ratio of 1:2, so there needs to be twice as many fiction books as nonfiction.
If we add 6 fiction books, we have 24 fiction books. We can now set up this equation:

Now we cross multiply

We can solve for x by dividing both sides by two, so:
x = 12. There will be 12 nonfiction books.
