Maria has lunch at a restaurant. If her bill was $11.81 and Maria wants to leave a 22% tip,what is a reasonable estimate for the amount she would leave for the tip?

What I got for the tip was: $2.60
This is what I did:
I made a proportion, x being the tip

22 x
----= ------ <------- here I did cross products (22*11.81=100x)
100 11.81

259.81=100x <-------- then I did inverse operations to solve the equation

x= 2.5982 <------- then I rounded since we're working with money

x= $2.60

Hope this helps :)

my way is easier
11.81÷100=0.1181
then 0.1181×22=2.5982
then round up because we r using money
so the tip will be
$2.60
