Answer:The number of minutes that Alexandra talked on her cell phone is 120
Step-by-step explanation:
A cell phone company charges a flat rate of 4.75 per month with an additional charge 0.19 per minute. Assuming the total number of minutes of call made for the month is represented by x and the total cost of x minutes of call is y, then
y = 0.19x + 4.75
To determine how many minutes that Alexandra talked on her cell phone if his monthly bill was 27.55, we would substitute y = 27.55 into the equation. It becomes
27.55 = 0.19x + 4.75
0.19x = 27.55 - 4.75 = 22.8
x = 22.8/0.19 = 120 minutes.
Question:
The local community theater sold a total of 240 tickets for Saturday night’s performance. They sold 180 more full-price tickets than discount tickets. Which system of equations can be used to model this situation?
Answer:


Step-by-step explanation:
Given

Represent the number of full price with x and discounted price with y.
From the question:
x = 180 more than y
So:

Also, a total of 240 were sold.
So:

Hence, the equations are:


Solving further;
Substitute 180 + y for x in 


Solve for 2y


Divide through by 2

Recall that: 


Hence:
<em>Full Price = 210</em>
<em>Discounted = 30</em>
