$20 - 4 \times 4 \div 2 + 3$

Using BODMAS formula, we see that we have first divide, then multiply, then add and finally subtract
So
$20 - 4 \times 4 \div 2 + 3 \\ = 20 - 4 \times 2 + 3 \\ = 20 - 8 + 3 \\ = 23 - 8 \\ = 15$

Please help find the interest?!

You want to calculate the interest on $300 at 9% interest per year after 4 month(s). The formula we'll use for this is the simple interest formula, or:

Where:

P is the principal amount, $300.00.

r is the interest rate, 9% per year, or in decimal form, 9/100=0.09.

t is the time involved, 4....month(s) time periods.

Since your interest rate is "per year" and you gave your time interval in "month(s)" we need to convert your time interval into "year" as well.

Do this by dividing your time, 4- month(s), by 12, since there's 12 months in 1 year.

So, t is 0.333333....year time periods.

To find the simple interest, we multiply 300 × 0.09 × 0.333333 to get that:

The interest is: $9.00

Usually now, the interest is added onto the principal to figure some new amount after 4 month(s),

or 300.00 + 9.00 = 309.00. For example:

If you borrowed the $300.00, you would now owe $309.00
