Problema Solution
Jill gets her cable service through Dish Network and she pays $35 extra dollars a month for watching 7 movies on demand. Jill wants to know how much less it would be to only watch 5 movies on demand.
If y=$35 when x=7, find y when x=5
Answer provided by our tutors
We have to assume that the cost for each movie is the same, therefore each movie costs:
35 / 7 = 5
If each movie costs $5 and Jill wants to watch only 5 movies, then the total cost would be:
5 * 5 = 25
Jill wants to know how much less it would cost to watch only 5 movies, so we subtract the two costs:
35 - 25 = 10
It would therefore cost Jill $10 less to watch only 5 movies on demand.
