I believe the answer is m=30
Step-by-step explanation:
How I got this answer:
first cross multiply
9(m+3) = 11(m-3)
9 m - 11 m = -33 -27
-2m = -60
m= 30 - (Check if the solution is in the defined range).
Answer:
3 nights
Step-by-step explanation:
Set up an equation that represents the problem:
y = 1.25x + 3.95
Where y is the total cost and x is the number of additional nights you rent the movie
Substitute:
7.70 = 1.25x + 3.95
Subtract 3.95 on both sides:
7.70 = 1.25x + 3.95
-3.95 -3.95
3.75 = 1.25x
Divide by 1.25 on both sides:
3.75 = 1.25x
/1.25 /1.25
3 = x
Therefore, you kept the movie for 3 additional nights.
