Please help me with this!! Will give brainliest and thanks you! I need this by today!! PLEASE NO TROLL. :( ALSO EXPLAIN plz.

$144 interest

Step-by-step explanation:

SInce it is a simple interest you have to solve like this

Principal x Interest rate x term

so it will be

3,000 x 4.8% x 1

= 144$ interest in one year without any withdrawal.

According to the poster you have to invest $3000 or more, and 3,000 is the minimum principal amount so it will yield the minimum interest that you could get in a year.

I hope that this could help :)

144 Dollars

Step-by-step explanation:

Apply the formula of simple interest:

total interest = Principal (3,000) . Interest rate in decimal ( 0,048) . Amout of time the rate was applied per year (1)

So, will be:

I = 3000 . 0,048 . 1

I = 144

3000 + 144 = 3144 is the total amount

The amout of interest is 144

$6.42

step-by-step explanation:

hello!

to begin with, we're given that on earth, a rock weighs 20 pounds, and while on jupiter, that same rock weighs 42 pounds. now, we're trying to find the weight of a rock that weighs 10.5 pounds on earth, on jupiter.

to solve this, first, set up a proportion, cross-multiply, and solve it algebraically.

setting up the proportion is the hardest and the most confusing part of the problem, but it's simple.

if on earth, the rock weighs 20 lbs, and on jupiter it weighs 42 lbs, our first part of our proportion is 20/42 lbs. the second part has to be equal to each other. this means that 10.5 has to be on the numerator of the fraction, and x, the value we're trying to find, has to be on the denominator. remember that the rock weighs 10.5 lbs on earth, and we're trying to find the weight of it on jupiter (which is x).

20/42 = 10.5/x

next, you would cross-multiply.

20x = 42(10.5)

20x = 441

now, solve it algebraically by using division.

x = 22.05 lbs

this can be rounded to 22.1 lbs.

therefore, the weight of the rock on jupiter is 22.1 lbs, the fourth choice.
