Christine can buy a new snowboard for $ She will still need to rent boots for $8.50 a day. She can rent a snowboard and boots for $18.25 a day. How many days would Christine need to rent both the snowboard and the boots to pay as much as she would if she buys the snowboard and rents only the boots for the season?

Let d represent the number of days.
18.25d = d
Subtract 8.5d
from both sides.
18.25d – 8.5d = d – 8.5d
9.75d = 136.5
Simplify.
9.75d = 136.5
Divide both sides by 9.75.
9.75
9.75
d = 14
Christine would need to rent both the snowboard and the boots for 14 days to pay as much as she would have if she had bought the snowboard and rented only the boots.

Let m represent the number of minutes.
75 = m
Subtract 40
from both sides.
75 – 40 = 40 – m
35 = 0.10m
Simplify. m
0.10 =
Divide both sides by 0.10.
350 = m
If you are going to use more than 350 minutes, it will be cheaper to subscribe to the unlimited plan.
