To avoid a service​ fee, your checking account balance must be at least ​$500 at the end of each month. Your current balance is
seraphim [82]

Answer: At least $91.91

Step-by-step explanation:

From the question, we are informed that to avoid a service​ fee, the checking account balance must be at least ​$500 at the end of each month.

Since the current balance is ​$525.17 and $117.08 has been spent, the balance will now be:

= $525.17 - $117.08

= $408.09

Since the checking account balance must be at least ​$500 at the end of each month and we currently have $408.09, this means that there will still be a need to add $91.91.

= $500 - $408.09

= $91.91

At least $91.91 must be added to avoid the fee.

I've been sitting on this problem for 2 hours! AND I STILL DON'T KNOW WHAT THE HECK IT ISSS!!!!
MArishka [77]

Answer:

A

Step-by-step explanation:

Use foil to expand it.

y = 4 (x^2 + 7x - 9x - 63)     Combine the like terms on the right.

y = 4(x^2 - 2x - 63)              Use the distributive property to remove the brackets.

y = 4x^2 - 8x - 4*63            Combine the two multiplied factors on the right.

y = 4x^2 - 8x - 252              4* 63 = 252

The answer is A
