Your Principal, P, is $400. Your interest rate, expressed as a decimal, is 0.03. Here, n is 1, since there is just 1 compounding period per year.

How much would you have after 16 years under such circumstances?

A = Amount = $400(1+0.03)^16. => $400 (1.03)^16 = $400(1.60)

Thus, you would have accumulated $641.88 after 16 years. Sounds like a pretty good deal to me. ;)

horsena [70]

Answer: $1\dfrac{3}{8}\ \text{inch}$

Step-by-step explanation:

Given

Rainfall in September is $\frac{7}{8}$ inch

Rainfall in October is $2\frac{1}{4}$ inch

Convert mixed fraction into fraction

$\Rightarrow 2\dfrac{1}{4}=\dfrac{9}{4}\ \text{inch}$

Difference between the two gives that how much more rain fall in October compared to September

$\Rightarrow \dfrac{9}{4}-\dfrac{7}{8}\\\\\Rightarrow \dfrac{18-7}{8}\\\\\Rightarrow \dfrac{11}{8}\ \text{inch or}\\\\\Rightarrow 1\dfrac{3}{8}\ \text{inch}$

solmaris [256]

Answer:

5 pens = 15$ and 4 pencils = 4$

Step-by-step explanation:

7-3=4, so 4 pens is 12$

12/4 = 3, so 1 pen = 3$

Remove the pens from the equation

7x3=21

24-21=3

3/3=1, so each pencil costs 1$
