Wendy bought 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 how many gallons wendy would need to bring. let n represent the number of groups of ten people.

X=the amount Wendy would need to bring
5= 5 gallons of iced tea
n= the number of groups of 10 people
2= 2 gallons per 10 people

2n+5=x

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 gallons 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

Hope this helps.

The answer is (2b+1)(3b-4)
