Writing Equations from Word Problems
1.) I am comparing two different delivery
food services, Company A charges $30 per
meal and a membership fee of $150 while
Company B charges $20 per meal and a
membership fee of $300. Write and solve an
equation to find the number of meals it will
take for both deals to cost the same amount
of money.
