If the principal is $350 and the interest rate is 3 percent, what is the simple interest earned in one year? simple interest = p × r × t select one of the options below as your a. $10.50 b. $30.25 c. $105

The option A. $10.50 is correct

Step-by-step explanation:

Principal = $350

Rate = 3%

⇒ Rate = 0.03

Time = 1 year

Now, Simple Interest is given by the formula : Principal × Rate × Time

Therefore, Simple Interest = 350 × 0.03 × 1

⇒ Simple Interest = $10.50

Hence, The option A. $10.50 is correct

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.
