Alright, let's analyze Poseletso's sales for the first four weeks, as shown in the table. To determine how many of each item she sells per month and on average, we will perform the following steps for each item:
1. Calculate the total sales for each item over the four weeks.
2. Calculate the average sales per week for each item.
Let's go through each item step-by-step:
1. Blue Pens:
- Week 1: 11
- Week 2: 14
- Week 3: 12
- Week 4: 23
- Total for the month: [tex]\(11 + 14 + 12 + 23 = 60\)[/tex]
- Average per week: [tex]\(60 / 4 = 15.0\)[/tex]
2. Green Pens:
- Week 1: 5
- Week 2: 17
- Week 3: 10
- Week 4: 7
- Total for the month: [tex]\(5 + 17 + 10 + 7 = 39\)[/tex]
- Average per week: [tex]\(39 / 4 = 9.75\)[/tex]
3. Pencils:
- Week 1: 20
- Week 2: 21
- Week 3: 43
- Week 4: 38
- Total for the month: [tex]\(20 + 21 + 43 + 38 = 122\)[/tex]
- Average per week: [tex]\(122 / 4 = 30.5\)[/tex]
4. Rulers:
- Week 1: 9
- Week 2: 13
- Week 3: 6
- Week 4: 22
- Total for the month: [tex]\(9 + 13 + 6 + 22 = 50\)[/tex]
- Average per week: [tex]\(50 / 4 = 12.5\)[/tex]
5. Erasers:
- Week 1: 5
- Week 2: 5
- Week 3: 6
- Week 4: 2
- Total for the month: [tex]\(5 + 5 + 6 + 2 = 18\)[/tex]
- Average per week: [tex]\(18 / 4 = 4.5\)[/tex]
6. Calculators:
- Week 1: 1
- Week 2: 6
- Week 3: 5
- Week 4: 8
- Total for the month: [tex]\(1 + 6 + 5 + 8 = 20\)[/tex]
- Average per week: [tex]\(20 / 4 = 5.0\)[/tex]
Therefore, the average sales per month for each item Poseletso sells are as follows:
- Blue Pens: 15.0 per week
- Green Pens: 9.75 per week
- Pencils: 30.5 per week
- Rulers: 12.5 per week
- Erasers: 4.5 per week
- Calculators: 5.0 per week
