Three friends decide that they each want to be able to buy a new bike in four years. IIiana puts $500 in a savings account with a simple interest rate of 4%. Joann invests S515 in a standard savers account with a simple interest rate of 3%. Cyndy invests $500 in a junior achievers account with a 3.5% compound interest rate.
Using the formula - Prt for simple interest and A-P(1+r) for compound interest, who will have the most money to s

1. a new bike at the end of the four years?
2. Joann will have the most money, $576.80 for the bike
3. Cyndy will have the most money, $580.00 for the bike.
4. Cyndy will have $576.80, the most money for the bike
5. Wana will have $580.00, the most money for the bike.

Iliana will have the most money, with a total of $580

Step-by-step explanation:

We can find the amount of money that each one will have using the formulas of interest:

For Iliana and Joann, simple interest: Total money = P + P*r*t

For Cyndy, compound interest: Total money = P*(1+r)^t

So, using the time of four years, we can calculate the total money of each one:

Iliana: P = 500 and r = 0.04:

Total money = 500 + 500*0.04*4 = $580

Joann: P = 515 and r = 0.03:

Total money = 515 + 515*0.03*4 = $576.8

Cyndy: P = 500 and r = 0.035:

Total money = 500*(1+0.035)^4 = $573.7615

So Iliana will have the most money, with a total of $580

i can you answer this question sweetie!

step-by-step explanation:

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.
