1) What is the simple interest if Principal = $100, Rate = 5% and time = 3 months? 2) Find the simple interest given that Principal = $900, Rate = 5% andd Time =1 year 4 months.

1. 1.25, 2. $60

Step-by-step explanation:

1. 100 x .05=$5 interest/year

$5/12=.42 interest per month

.42x3 =1.25 interest for 3 months

2. 900 x .05=$45 interest/year

$45/12=3.75 interest/month

$3.75 x 16 months=$60 interest/16 months

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
