We can calculate the percent by dividing each expense by the total income and multiplying it by 100
a) If we add them in a table, we obtain the following:
b) Megan probably doesn't spend on Housing and Utilities because she still lives with her parents and they don't charge her rent.
c) Megan probably spends $150 on public transportation, like the subway or bus
d) Megan probably saves a large percentage because she doesn't spend on housing utilities and also she spends very little on food, clothing, health, and personal care.
e) Let's create a new budget where her transportation expenses are now $195 (because she's now paying a car) plus $100 for gas. So that's a total of $295 for transportation.
