Answer:
7 Months
Step-by-step explanation:
x=number of months
how much is deducted total=number of months times amount deducted per m onth
amount deducted per month=45
number of months=x
how much deducted total=45x
460-deducted total is more than 100
460-45x>100
solve for x
add 45x to both sides
460>100+45x
subtract 100
360>45x
divide both sides by 45
8>x
answer is 7 months
if he does 8 months, then he will have exatly 100 and 100 is noe more than 100

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.

Use the expression:
y₂ - y₁
--------
x₂ - x₁
choose one set to be your ₁, and the other to be your ₂. Plug them in
3 - 2 1
------- = ----------
5 - (-2) 7
your slope will be 1/7
hope this helps
