Thus, a=4 cases.
ii.
To explain the reason behind rounding off to the greater whole number.
ii.
Answer to Problem 3P
The answer is rounded to a whole number because the vegetable cases cannot be in decimal or fraction.
Explanation of Solution
Given:
Cost of l case of vegetables= $10.68
Club’s budget= $50 Cases bought= 4
Calculation:
From the solution of part a, we get
Here we take a=4 because cases are whole numbers and we are getting answer in decimels. Hence we cannot buy the 5th case since the 5th case would cost $ 0.32 more, so in $50 we round the 4.68 cases to 4 cases.
