Answer:
See explanation below
Explanation:
For a certain number of videos rented, the cost would be same. So until that number of videos, one plan would be better. After than part, another plan would be better.
Lets check.
Let the number of video viewed be "x"
For Plan 1:
fixed rate of $7 PLUS 2.50 for x videos
So we can write:
7 + 2.50x
For Plan 2:
No fixed rate, only $4 per video for x videos, so we can write:
4x
Now, we equate and find x:
7 + 2.50x = 4x
4x - 2.5x = 7
1.5x = 7
x = 4.67
Lets check cost for 4 videos:
Plan 1 ----- 7 + 2.5(4) = $17
Plan 2 ------- 4(4) = $16
Lets check cost for 5 videos:
Plan 1 ----- 7 + 2.5(5) = $19.5
Plan 2 ---- 4(5) = $20
So, we can say if you were to rent 1,2,3, or 4 videos per month, you should go with Plan 2 since it will be cheaper. If you rent 5 or more videos per month, then you should go with Plan 1 as that would be cheaper.
