Julia will earn $240 in 5 years from the interest.
Interest is the cost of borrowing money. The borrower pays interest, and the lender receives it.
Given that an equation I = 48t showing the interest earned by Julia in t years,
We need to find how much she earned in 5 years,
To find the same just put t = 5 in the equation,
I = 48 × 5
I = 240
Hence Julia will earn $240 in 5 years from the interest.

Find the interest due on $800 at 12% for 120 days.
Answer:
$32
Step-by-step explanation:
To find the interest due, you will use an interest formula.
The formula will be: Interest= P · r ·
P represents our principal amount, R is our rate of interest, and N is the number of days (out of 365 which is a year).
In this situation,
$800 will be our P amount, 12% will be our R, and 120 will be our N.
This will give us:
Interest= 800 · 0.12 ·
Before we go on, I would like to clarify 12% goes out of a hundred. To find the decimal form, you will divide 12 over 100. By doing this, you will find yourselves having 0.12 (our rate of interest).
When you solve our new formula equation, you will get a long decimal number consisting of 31.5616... Remember a decimal will be rounded if it is 5 or above, if it less than 5 it will not be rounded. In this case, we got 31.5, so we round; getting us 32.
Our answer will then be $32
Answer:
Area model is one of a simple step to understand the given situation. So to make it simple, we need to decompose the number.
given number = 4.6 and 3
First we need to get the whole number and start multiplying:
Whole number of 4.6 => 4
whole number of 3 => 3
Now, let’s start multiplying the whole number
=> 4 x 3
=> 12
Then let’s multiply the remaining decimal:
=>.6 x 3
=> 1.8
Then add
=> 12 + 1.8
= 13.8
we know that
The area model for multiplication is a pictorial way of representing
multiplication. In the area model, the length and width of a rectangle
represent factors, and the area of the rectangle represents their product
So
in this problem
the factors are
l e n g t h 4.6 w i d e 3
decompose the number
4.6
4.6 = ( 4 + 0.6 ) A r e a o f r e c t an g l e = A r e a r e ct a n g l e 1 + A r e a re c t a n g l e 2 = ( 4 + 0.6 ) ∗ 3 = 4∗ 3 + 0.6 ∗ 3 = 12 + 1.8 = 13.8
see the attached figure to better understand the problem
therefore
the answer is
the product of
4.6
and
3
is equal to
13.8
