If five cookies cost $0.30 how much would 30

Question

I don't understand this at all I need tips on how to solve word problems I try everyday still don't understand word problems 

Answer 1

Use this conversion factor:

 

5 cookies = $0.30

 

 

If we multiply both sides of this conversion factor by 6, we get

 

6(5 cookies) = 6($0.30)

 

30 cookies = $1.80

 

 

30 cookies cost $1.80
