Sarah earns $400 per week and spends 15% of her earnings on transportation. How much does Sarah spend on transportation every week? *

Think of it like this: ?/400$ = 15/100. We are trying to find 15 % of 400, so that’s what the “?” represents.
thinking of it like fractions, cross multiply the numbers you have in this situation (400x15) =6,000
then you divide that answer by the number left (100)
(6,000 / 100) = 60

So the answer is 60$, 15% of 400$ is 60$
