Answer:
$380
Step-by-step explanation:
380$
Multiply 400*5%=20
Then subtract 400-20=380
2/5 okkkkkkkkkkkkkkkkkkkkk
15
First add 20 to both sides to get x/3 = 5
Then multiply both sides by 3 to get 15.
You can check it by substituting it into the equation
15/3 - 20 = -15
5 - 20 = -15
-15 = -15
answer:
y = 19.2 when x = 8
So the answer is 8
