A group of friends equally split the dinner bill shown. If each person paid $16, how many friends paid?

Akimi4 [234]

Answer:

16/y = x

Step-by-step explanation:

You cannot solve for the question yet. However, you can create an equation!

we know that each person paid 16 dollars.

We don’t know how much the bill was or how many people were there.

So out equation looks like;

z/y = x

z * x = y

z = how much each person paid.

y = how much each person paid.

x = how many people paid.

Substitute with what we know.

16/y = x

16 * x = y

Now you will be able to substitute for either x or y to find either answer.

$\bf \qquad \qquad \textit{sum of a finite geometric sequence} \\\\ S_n=\displaystyle\sum \limits_{i=1}^{n}\ a_1\cdot r^{i-1}\implies S_n=a_1\left( \cfrac{1-r^n}{1-r} \right)\quad \begin{cases} n=n^{th}\ term\\ a_1=\textit{first term's value}\\ r=\textit{common ratio} \end{cases} \\\\[-0.35em] ~\dotfill$

$\bf S_{20}=\displaystyle\sum \limits_{n=1}^{\stackrel{\stackrel{n}{\downarrow }}{20}}~\stackrel{\stackrel{a_1}{\downarrow }}{3}(\stackrel{\stackrel{r}{\downarrow }}{1.5})^{n-1}\implies S_{20}=3\left(\cfrac{1-1.5^{20}}{1-1.5} \right)\implies S_{20}=3\left(\cfrac{1-\stackrel{\approx}{3325.3}}{-0.5} \right) \\\\\\ S_{20}=3\left(\cfrac{-3324.3}{-0.5} \right)\implies S_{20}=3(6648.6)\implies S_{20}=19945.8$
