Answer:
x=2
Step-by-step explanation:
For the
national mobile, you have 300 texts for 9.99 dollars whereas for airtime, you
have 500 texts for 17.99 dollars.
9.99
dollars/300 texts = 0.0333 dollars per text
17.99
dollars/500 texts = 0.036 dollars per text
Choose the
cost which has the lowest rate. If you really like to travel to other places
and you need to budget, you will choose the national mobile rate. It is cheaper
and 300 texts is a lot. However, if you want to travel including using your
mobile texts during air transportation, you need to buy the 17.99 dollars. It’s
a bit expensive but the number of texts is a lot. Divide the cost by the number
of texts. For costing purposes, its smarter to choose the national mobile rate.
