A friend asks to borrow $250 for 18 months and pays 12% annual simple interest how much interest will you earn

$45

Step-by-step explanation:

Simple interest is calculated as Principal x Rate x Time/100

From the information given,

Principal = $250

Rate = 12% = 12/100 = 0.12

Time = 18 months; because time is given in months, we divide by 12; time is therefore stated as 18/12.

Step 2: Plug the values into the formula:

Simple interest = 250 x 0.12 x 18/12

= $45

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
