Algebraic expressions are expressions that use numbers and variables
The value of A is 65/64
<h3>How to determine the value of A</h3>
The expression is given as:

Rewrite the expression as:

Factor out 2^x

Rewrite as product

The expression to compare with is given as: A * 2^x.
So, we have:

Divide both sides by 2^x

Take LCM


Hence, the value of A is 65/64

Answer: 1692
Step-by-step explanation:
Formula to find the sample size :

Given : Confidence level : 
⇒ significance level =
z-value for 90% confidence interval (using z-table)=
Prior estimate of the population proportion (p) of customers who keep up with regular vehicle maintenance is unknown.
Let we take p= 0.5
Margin of error : E= 2%=0.02
Now, the required sample size will be :

Simplify , we get

Hence, the required sample size = 1692
