PLEASE HELP Calculate the simple interest on each amount and the total amount at the end.

a) a loan of $250 at 5% per year over three years

b) a deposit of $500 that pays 3.5% per year over five years

c) a loan of $1200 at 6.9% per year over four years

d) a deposit of $2550 that earns 3% interest over 30 months

e) a loan of $5000 at 8% per year over 39 weeks

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.

step-by-step explanation:

what i would say the best answer is a. 40.5
