Pineapples are on sale for $2 each, but customers can buy no more than 5 at this price.
For pineapples bought at the sale price, the total cost, y, is directly
proportional to the number bought, x. This function can be modeled by y = 2x.
What is the domain of the function in this situation?
A. {0, 2, 4, 6, 8, 10)
B. All positive numbers, x > 0
O C. {0, 1,2,3,4,5)
D. {0, 1, 2, 3, 4, ...}

9514 1404 393

  C. {0,1,2,3,4,5)

Step-by-step explanation:

The domain of the function is the possible numbers of pineapples that could be bought at the indicated price. That will be a non-negative integer less than or equal to 5:

  {0, 1, 2, 3, 4, 5)

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
