Answer:
Try solving 6(n-5)-2.
Step-by-step explanation:
I believe this can be set up as 6(n-5)-2. The difference of a number and five can be represented by n-5. If this needs to be multiplied by 6 (hence 6 times), it would become 6(n-5). Two less than that is represented by -2. Thus, two less than six times the difference of a number and five is 6(n-5) -2, which, when n=9 is plugged in, looks like 6(9-5) -2. Follow PEMDAS from there.
C + w = 35
w = 2/5c
c + 2/5c = 35
5/5c + 2/5c = 35
7/5c = 35
c = 35 / (7/5)
c = 35 * 5/7
c = 175/7
c = 25 <=== there were 25 chocolate milks sold
c + w = 35
25 + w = 35
w = 35 - 25
w = 10.....there were 10 white milks sold
