Discussion Overview

The discussion revolves around a rate problem involving Emily's sales in a cafeteria. Participants explore how to calculate the time it would take for her to sell specific quantities of various food items based on her average sales rates during a 30-minute break.

Discussion Character

  • Homework-related
  • Mathematical reasoning

Main Points Raised

  • Emily sells an average of 16 Banana milkshakes, 13 baked macaronis, 5 Cauliflower Fried Rices, and 25 Blueberry Muffins in 30 minutes.
  • Some participants calculate the sales rate per minute for each item, determining that she sells 0.5 Banana milkshakes, 0.4 baked macaronis, 0.17 Cauliflower Fried Rices, and 0.8 Blueberry Muffins per minute.
  • One participant asks how long it would take Emily to sell 50 Banana milkshakes based on her sales rate.
  • Another participant emphasizes that the original question requires calculating the time for all items, not just the Banana milkshakes.
  • A later reply clarifies that the initial response was intended to guide the problem-solving process rather than provide a direct answer.

Areas of Agreement / Disagreement

Participants appear to have differing interpretations of the problem's requirements, with some focusing solely on the Banana milkshakes while others argue for a comprehensive approach to all items. The discussion remains unresolved regarding the best method to calculate the total time needed.

Contextual Notes

Some assumptions about the sales rates and the total quantities required may not be explicitly stated, and the discussion does not resolve how to integrate the calculations for all items into a single solution.

a. Emily works in the canteen and sells on average 16 Banana milkshakes,
13 baked macaronis, 5 Cauliflower Fried Rices, 25 Blueberry Muffins in one break.
Each break at the cafeteria is 30-min-long.

How long is it likely to take Emily to sell
50 Banana Milk Shakes,
34 Baked Macaronis,
25 Cauliflower Rices and
43 Blueberry Muffins?

So in 30 min, she sells
16 Banana M
13 Baked Mac
5 Clf Rice
25 Blueberry Muff...

Dividing each one by 30 we get how much she sells in 1 min:
16/30 = 0.5 Banana M per min
13/30 = 0.4 B Mac per min
5/30 = 0.17 Clf Rice per min
25/30 = 0.8 Blueb Muff per min

Sounds good... so if Emily sells 0.5 Banana Milk Shakes per minute, how long does it take her to sell 50?

not quite, the whole question is
How long is it likely to take Emily to sell
50 Banana Milk Shakes, 34 Baked Macaronis, 25 Cauliflower Rices and 43 Blueberry Muffins?
 
So you did not understand what Klas Van Arsen said! He was not handing you the answer he was showing you how to do the problem. If she makes 1/2 banana milk shake per minute, how long does it take to make 50? If she sells 0.4 baked macaroni per minute, how long does it take to make 34? Do that for each if the others.
