Show Worked Solution

$\text{Total royalty earnings (B8)} = $4200$

$\text{Royalty rate per stream (B5)}=$0.004$

$\text{Let the number of streams (B4)}=N$

$\text{Total royalty earnings} = \text{Number of streams} \times\text{Royalty rate per stream}$

$\text{B8}$	$=\text{B4}^*\text{B5}$
$4200$	$=N\times 0.004$
$N$	$=\dfrac{4200}{0.004}$
	$=1\,050\,000$

$\text{Yuki had 1 050 000 streams in the next quarter}$

\(\text{B8}\)	\(=\text{B4}^*\text{B5}\)
\(4200\)	\(=N\times 0.004\)
\(N\)	\(=\dfrac{4200}{0.004}\)
	\(=1\,050\,000\)
