Answer: 4.1375
Step-by-step explanation:
15% of 11.50 is 1.725 so subtract 11.50 - 1.725 , you get 9.775 , you subtract 1.50 from 9.775 and get 8.275 , you divide by 2 because there is two servings and you want to find the answer for one , so 8.275 / 2 = 4.1375
6(y+3) = 72
6y + 18 = 72
6y = 72 - 18
6y = 54
y = 54/6
y = 9
