The simple interest formula is l=prt where l represents simple interest on an amount p for t years at a rate of r where r is expressed as a decimal. what is the amount of money p that will generate $40 in interest at a 10% interest rate over 5 years

First solve for p.

Then insert the data.

Hope this helps.

r3t40

$80

Step-by-step explanation:

Given : Interest amount :

The rate of interest :

Time period : years

The simple interest formula is

, where l represents simple interest on an amount p for t years at a rate of r where r is expressed as a decimal.

Substitute all the values in the  formula , we get

Hence, the amount of money p that will generate $40 in interest at a 10% interest rate over 5 years= $80

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

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.
