area = 140

length = 2w-6

Area of a rectangle = l*b

⇒ 2w-6*w=140

$600 , 8% , 1 month find the simple interest
Vlad [161]

Answer:

$4

Step-by-step explanation:

Simple interest = Principal *rate *time

S.I = P*r*t

Principal ; p = $600

rate ; r = 8% or 0.08 as a decimal

time; t = 1 month , however, convert this to years by dividing by 12;

t = 1 / 12

Next, plug in the numbers into the formula;

S.I = 600 *0.08*\frac{1}{12}

S.I = 4

Therefore simple interest in 1 month becomes $4
