Check the picture below.

F = sales for Friday

we know that the total of weekend sales for Germany was F + 317 + 405.

we also know that 405 is really 37.19% of that amount, say "x", which is the 100%, so

\begin{array}{ccll} amount&\%\\ \cline{1-2} 405&37.19\\ x&100 \end{array}\implies \cfrac{405}{x}=\cfrac{37.19}{100}\implies 40500=37.19x \\\\\\ \cfrac{40500}{37.19}=x\implies 1089~\approx ~ x \\\\[-0.35em] ~\dotfill\\\\ \stackrel{friday}{F} + \stackrel{sat/sun}{317} + \stackrel{monday}{405} \approx 1089\implies F +722 \approx 1089\implies \boxed{F\approx 367}

Find the percent of change. Original: 80, new: 64
lara31 [8.8K]
Hi there!

To find the percent of change we can use the following formula:
\frac{new - old}{old} \times 100\%

Let's fill in our data
\frac{64 - 80}{80} \times 100\% =

Subtract
\frac{ - 16}{80} \times 100\% =

Divide
- 0.2 \times 100\%

And finally multiply
- 20\%

Hence, the percent of change is negative 20%.
