Raul has $460 in his checking account. Each month, $45 is automatically deducted from his account to pay for his cell
phone plan. He makes no other deposits or withdrawals. He wants to always have more than $100 in his account
What is the greatest number of months he can pay for his cell phone and still have more than $100 in his account?
7 months
8 months
9 months
10 months

Answer 1

Answer:

answer b 8 months

Step-by-step explanation:

you can subtract 100 from 460, to get 360 which if you take 45/360 you would get 8, and have 100 dollars still that you took out

Answer 2

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
