Answer:
1. D
2. B
Step-by-step explanation:
<u>Question 1:</u>
We can get Avon's earnings using the equation 
Where W is his earnings
HR is the regular hours (40 hours in this case)
V is overtime hours (hours over 40, 45.5 - 40 = 5.5 hours)
B is bonus (no bonus)
T is tips ( $100 tips, given)
and R is the rate (which is $5 per hour)
<em>Substituting the given info into the equation, we get:</em>
<em>
</em>
<em>So avon's earnings are $341.25</em>
<em>Answer choice D is right.</em>
<u>Question 2:</u>
The other employee needs to work
hours @ $15 per hour to equate or surpass $428. So we can set up the equation shown below and solve for x:

Rounded to 1 decimal place, this is about 28.5 hours
Answer choice B is right.
Answer:
Equations:
--- Cindy
--- Ruben
Solution to equation:
Time they have the same amount: 14 minutes
Number of cards they have at that time: 140 flashcards
Step-by-step explanation:
Solving (a): Variables and what they represent
The variables to use are x and y
Where x represent the minutes and y represents the number of flashcards in x minutes
Solving (b): System of linear equation
Cindy:

per minute
Total number of flashcards (y) in x minutes is:



Ruben:
per minute
Total number of flashcards (y) in x minutes is:



Solution to Equations:
Time they have the same amount.
To do this, we
expressions
i.e.

Collect Like Terms


Number of cards they have at that time.
Here, we simply substitute 14 for x in any of the equations.
