Question

A telecommunication company charges a monthly basic subscription fee of $20 for their

post-paid services. For every 10 minutes or part thereof, the subscriber is charged $2.
If Dan has a monthly budget of $200, what is the maximum number of minutes that he
can use every month?

Answer 1

900 mins

Explanation:

basic charge = 20$

so let's subtract it from 200$

so he will have 180$ for the post paid usage.

every 10 minutes = 2$

with 180$, he can do 180/2 * 10

= 90*10=900min
