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?

The answer is 7 months.

Step-by-step explanation:

Raul has $460 in his checking account. Each month, $45 is automatically deducted from his account to pay for his cell phone plan.

He wants to always have more than $100 in his account.

Let the greatest number of months he can pay for his cell phone and still have more than $100 in his account be = x

So, equation representing this situation becomes:

Solving this we get

=>

=>

So, the answer is 7 months.

If we take months, then exactly $100 will be left but the condition says, more than $100 is needed, so we will take 7 months.

Therefore, the answer is 7 months.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
