Step-by-step explanation:
- Place value chart: 7 x 2.6 = 18 ones plus 2 tenths = 18.2
- Area model: 7 x 2.6 = 14 + 4.2 = 18.2
<h3>
Further explanation</h3>
Miles incorrectly gave the product of 7 x 2.6 as 14.42.
Let us use a place value chart or an area model to help Miles understand his mistake.
See the attached picture for the place value chart and area model.
<u>Place Value Chart</u>
7 x 2.6 is the same as 7 multiplied by 2 ones and 6 tenths. In other words, we see clearly that 7 multiplied by 2 plus 7 multiplied by 0.6.
- We prepare two columns of ones and tenths separated by dots.
- In the ones column, place two dots on each row until it reaches 7 rows. This means 7 times 2 equal to 14 dots.
- In the tenth column, place six dots on each row until it reaches 7 rows. This means 7 times 0.6.
- In the tenth column, every time it reaches 10 dots, it becomes 1 ones which are added to the dots in the ones column.
- There are 4 additional dots in the ones column as a result of each 10 dots in the tenth column. We add 14 dots with 4 dots and the result is 18 ones.
- The remaining dots in the tenth column will be added with all the dots in the ones column. There are two dots left so that it becomes 2 tenths.

<u>Area Model</u>
7 x 2.6 is the same as 7 multiplied by 2 ones and 6 tenths.
- Let 2 ones and 6 tenths as the length and 7 as the width of a rectangle.
- 7 x 2 ones = 14 ones or 14.
- 7 x 6 tenths = 42 tenths or 4.2.
- The area of the rectangle is 14 ones plus 42 tenths, or 14 plus 4.2.

Answer:
$ 17.63
Step-by-step explanation:
Given,
The sales of the salesperson are,
$15.50, $18.98, $16.8, $14, $18.50, and $22,
Sum of sales = 15.50 + 18.98 + 16.8 + 14 + 18.50 + 22 = 105.78
Also, the number of sales = 6,
Thus, the average sale = 

= $ 17.63
