Letter A company charges a flat rate of $129 (yearly) for AP and $7.99 for each HD movie rental.
1 answer:
c) You must rent 5 movies from each company to have equal bills.
d) The dollar amount would be $168.95 when the bills are equal which can be determined by putting x=5 in both function.
Step-by-step explanation:
Given,
Yearly charges of Letter A = $129
Per movie rent = $7.99
Let,
x be the number of rental movies.
A(x) = Yearly charges + Per movie rent*Number of movies rented
A(x) = 129 + 7.99x
Yearly charges of YR = $144
Per movie rent = $4.99
Y(x) = 144+4.99x
c) Solve the system of equations to determine how many movies you must rent from each company to have equal bills.
For equal bills;
A(x) = Y(x)
Dividing both sides by 3
You must rent 5 movies from each company to have equal bills.
d) What would be the dollar amount when the bills are equal? How did you get that answer?
We will use x=5 to check the dollar amount.
The dollar amount would be $168.95 when the bills are equal which can be determined by putting x=5 in both function.
