The algebraic expression that represents the total cost would be: A. 1.25r.
<h3>How to Write an Algebraic Expression?</h3>
Given that the number of donuts Rick buys for his family is represented by letter "r", and we also know that:
cost of each donut = $1.25.
Using an algebraic expression, we can create a mathematical expression that shows the total cost for Rick to by a given number of donuts for his family.
Thus:
1 donut = 1.25
r donuts would cost: 1.25 × r = 1.25r.
Therefore, the algebraic expression that represents the total cost would be: A. 1.25r.

Answer:
Step-by-step explanation:
Information given
represent the sample mean of amount of liquid
represent the standard deviation
sample size
represent the value that we want to check
t would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
System of hypothesis
We want to verify if the true mean for the amount of liquid is lower than 12 ounces, and the hypothesis are given by:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing we got:
