Question

susie is participating in a bake sale for a fundraiser. she baked 8 pies to sell. two pies weigh 105 g each, one pie weighs 106 g, two pies weigh 108 g each and the last three pies weigh 103.5 g, 102 g and 104.5 g. what is the average weight of the pies rounded to two decimal places? enter your answer in the box.

Explanation:

Step1: Calculate total weight

First, we find the total weight of all pies.

• 2 pies at 105 g: \(2\times105 = 210\)
• 1 pie at 106 g: \(1\times106 = 106\)
• 2 pies at 108 g: \(2\times108 = 216\)
• 3 pies: 103.5 g, 102 g, 104.5 g. Their sum: \(103.5 + 102 + 104.5 = 310\)

Total weight: \(210 + 106 + 216 + 310 = 842\)

Step2: Calculate average

There are 8 pies. Average weight = \(\frac{842}{8} = 105.25\)

Answer:

105.25
