To find out how much money sarah takes per month we divided her total income by 12.

Therefore, Sarah takes home $2750 per month.
To find out Sarah monthly for her home we multiply his total salary per month by .20:

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
