Answer:The equation wth x in the information can be written as
1/2 x = 38.5 , Upon solving, the number = 77
Step-by-step explanation:
Let the number Sara was thinking about be x
halving the number to get an answer = 38.5 can be expressed as
1/2 X = 38.5
The equation with x in the information can be written as
1/2 x = 38.5
solving it becomes
1/2 x= 38.5
x = 38.5 x 2
x=77
The number Sara was thinking about = 77
Using proportions, the selling prices are given as follows:
1. $46.92.
2. $15.29.
3. $17.16.
4. $20,280.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
To find the selling prices, we have to multiply the original prices by either 1.02(2% sales tax) or 1.04(4% sales tax), hence they are given as follows:
- 2. 14.99 x 1.02 = $15.29.
- 3. 16.50 x 1.04 = $17.16.
- 4. 19500 x 1.04 = $20,280.

Answer:
$34 and 77.8 miles
Step-by-step explanation:
The computation of the amount for traveling 25 miles is shown below:
Since it is given that the rental company charges $2.75 plus $1.25 for each mile
So for 25 miles, the cost you have to pay is
= $2.75 + 25 miles × $1.25
= $2.75 + $31.25
= $34
Now for traveling for $100, the miles should be traveled is
= ($100 - $2.75) ÷ 1.25
= 77.8 miles
Hence, the same is to be considered
