Question

write a linear equation that represents the number of days Emma can work and travel and still earn enough for her laptop?
earns $90 a day after deductions, works maximum of 40 days in July and August combined, day of travel will cost her $150, and the laptop she hopes to get is $700. help plz

Answer 1

inequation:
90x-150y>=700
x<=40
y<=62
x is the days she works and y is the days she travels.
equation:
90x-150y=700 (although the equation will be less accurate than the inequation)
