Step-by-step explanation:
We have
![\frac{800mL}{4.8L} \\\\\frac{0.8L}{4.8L}\\\\\frac{1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B800mL%7D%7B4.8L%7D%20%5C%5C%5C%5C%5Cfrac%7B0.8L%7D%7B4.8L%7D%5C%5C%5C%5C%5Cfrac%7B1%7D%7B6%7D)
The number of days d, he must use the gym to make the membership worthwhile is at least 21 days
Equation
Non members:
Cost of swimming per day = $5
Cost of exercise per day = $9
Total = $5 + $9
= $14
Members:
Yearly fee = $300
Exercise fee per day = $4
Swimming fee = $0
The number of days d, he must use the gym to make the membership worthwhile = $300 ÷ 14
= 21.42857142857142
Approximately,
21 days

Answer:
B. 40, 51.5, 88.5
Step-by-step explanation:
(5x - 4) + (2x + 3) + (3x- 4) = 180
10x - 5 = 180
10x = 185
x= 18.5
Substitute
5(18.5) - 4 = 88.5
2(18.5) + 3 = 40
3(18.5) - 4 = 51.5
