Question

Mr. blackwell tracks sales of ski equipment each week for a month. Complete the table to determine which week had the highest percent of ski equipment

Answer 1

The solved table has been attached as an image. And Week 2 recorded the highest % of ski equipment. Please see explanation below:

We have been given the following information:

• Ski Equipment Sales ($) for Week 2 and Week 4
• Percent of Total Sales for Week 1 and Week Week 3
• Total Sales for Week 1, Week 2, Week 3 and Week 4

We know that for a particular week:

Ski Equipment Sales ($) = Percent of Total Sales × Total Sales

Based on the above formula, for week 1:

Ski Equipment Sales ($) = Percent of Total Sales × Total Sales

⇒ Ski Equipment Sales ($) = 50% × 400

⇒ Ski Equipment Sales ($) = 200

For Week 2:

Percent of Total Sales =
`(Ski Equipment Sales)/(Total Sales)`

⇒ Percent of Total Sales =
`(175)/(250)`

⇒ Percent of Total Sales = 70%

For Week 3:

Ski Equipment Sales ($) = Percent of Total Sales × Total Sales

⇒ Ski Equipment Sales ($) = 65% × 300

⇒ Ski Equipment Sales ($) = 195

For Week 4:

Percent of Total Sales =
`(Ski Equipment Sales)/(Total Sales)`

⇒ Percent of Total Sales =
`(110)/(270)`

⇒ Percent of Total Sales = 41%

So now we know that percent of total sales is as follows:

Week 1: 50%

Week 2: 70%

Week 3: 65%

Week 4: 41%

Hence, highest percentage is for Week 2
