Question 796929
Wendy brought the lemonade and iced tea for the school picnic.
 Since more people like lemonade than iced tea, she brought 2 gallons of lemonade for every 10 people.
 She also brought 5 gallons of iced tea for people who don't like lemonade.
Write an algebraic expression to show the total number of gallows Wendy would need to bring.
 Let n represent the number of groups of ten people.
:
total = 2 gal per n groups of 10 + 5 gal of tea
f(n) = 2n + 5
