Answer:
You didn't put any numbers, but I'm going to assume it's 5 liters of natural oil for every 8 liters of synthetic oil and you're asking in order to make 936 liters of petrolyn oil, how many would need to be synthetic. In that case the answer would be 576
Step-by-step explanation:
( natural oil ) / ( synthetic oil ) = 5/8
Let x = liters of synthetic oil needed
936 - x = liters of natural oil needed
5/8=936-x/x
Multiply both sides by 8x
5x=8(936 - x)
5x=7488 - 8x
13x=7488
x=576

Answer:
13
Step-by-step explanation:
To find the right answer, do her work in reverse
37 times 2 = 74
74 + 6 = 80
Barbara had started with the number 80
Now do the work the way the teacher asked her to do it
80 - 2 = 78
78 / 6 = 13
Hope this helps!
