at greenbrier bank, checking account customers earn 0.8% interest a month on their account balances, pay a $0.10 service fee per check, and pay a monthly $2.00 financial charge.

calculate the income earned on the checking account for a customer who writes 21 checks and maintains a minimum balance of $1,210.

a.
$4.27

b.
$5.58

c.
$6.42

d.
$7.35

B. $5.58

Step-by-step explanation:

In order to find the amount of income earned, we can set up an equation using a variable for the number of checks and the minimum balance:

Income earned = (.008)b - $0.10c - $2.00, where b = the minimum balance and c = the number of checks.

Since the customer writes 21 checks, c = 21 and maintains a minimum balance of $1,210, b = 1210, we can fill in the variables and solve the equation:

Income earned = (.008)(1210) - (0.10)(21) - 2 or 9.69 - 2.10 - 2  = $5.58

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
