Answer:
it cost $39.95 in a month when you use the internet for 14 hours
Step-by-step explanation:
internet company charges $4.95 per month plus $2.50 for each hour
Let x be the amount of hours internet used
for 1 hour, charge is 2.50
for x hours , charge is 2.50x
To get linear equation we use y=mx+b
m is the slope and b is the fixed cost
fixed cost b= 4.95 and slope m = 2.50
So equation becomes y = 2.50x + 4.95
we need to find the cost y for 14 hours
So we plug in 14 for x and find out y
y = 2.50(14) + 4.95= 39.95

- Area model: 7 x 2.6 = 14 + 4.2 = 18.2

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.
