The correct answer to your question is going to be option C. if we look at the equation 4x + 7 = 31, we can see that 4x stands for a number that changed depending on how much of something x can be. the 7 in the equation stands for something doesnt change depending upon variables how much or how little x will be. knowing this, if we look at option C we read that each phone case cost $7 while $4 is how much it costs to ship. since this problem is about how many $4 phone cases Taliba can get, C would incorrect because they say that $7 is the post of each phone case.

- The contribution of the friend's company is of: $60.
- The account's balance after 20 years will be of: $130,694.36.
- The total deposits after 20 years are given as follows: $28,800 by the friend and $14,400 by the company.
- The interest earned during this entire period was of: $87,494.36.
<h3>How to obtain the balance?</h3>
The balance is obtained using the future value formula, which is presented as follows:

The meaning of each parameter is explained as follows:
- P is the total month deposit.
- n is the number of coupoundings per period, that is, compoundings per year.
- t is the number of years.
The deposits will be of:
- Company: $60, as it is half of the friend.
Then the parameter P is of:
P = 120 + 60 = 180.
The remaining parameters to obtain the balance after 20 years are given as follows:
r = 0.03, n = 12, t = 20.
Then the balance after 20 years is obtained as follows:


B = $130,694.36.
The total deposits will be of:
- Friend: 120 x 20 x 12 = $28,800.
- Company: half of friend -> $14,400.
The interest accrued is the balance subtracted by the total deposits, hence:
130694.36 - (28800 + 14400) = $87,494.36.

Answer:
1500 millimeters
Step-by-step explanation:
Half, meaning cut it by 1/2 of it's original value.
To cut it in half, we need to divide 27 by 2 to get the answer 13.5.
This makes sense because 14 + 14 = 28, and 13.5 + 13.5 = 27.
