Let's say you're renting a boat
Let h = number of hours you rent the boat
if it costs $46 per hour to rent a boat, then it will cost a total of 46*h or 46h dollars
Now let's say that you get a discount if you are a member. The membership fee is $86 leading to the discount hourly cost to be $25 per hour. If you rent for h hours, then you pay a total of 86+25h dollars
Writing 46h > 86+25h will represent cases when the nonmembership option is more expensive (and the membership option more cheaper). Solving for h will help determine when the membership option is cheaper.

Answer:
- Moana: 68 seed packets
- Afa: 27 calendars
Step-by-step explanation:
Let c represent the number of calendars sold. Then 95-c is the number of seed packets sold. The total revenue is ...
0.65(95-c) +1.50c = 84.70
0.85c = 22.95 . . . . . . . . . . . . subtract 61.75
c = 27
95 -c = 68
Moana sold 68 seed packets; Afa sold 27 calendars.
Since you use 9 tablespoons per 21 cups, you need to first divide 168 by 21 and get 8. Then you will take 8 times 9 and get 72 tablespoons of milk.
