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

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
