Question

A gift store stocks baseball hats in red or
green colours. Of the 35 hats on display
on a given day, 20 are green. As well,
18 of the hats have a grasshopper logo
on the brim. Suppose 11 of the red hats
have logos. How many hats are red, or
have logos, or both?

Answer 1

we can make a table

Answer 2

how so?

Answer 3

Total hats = 35
Green hats = 20
Red hats = Total hats - Green hats
Total logos = 18
Logos on red hats = 11
Logos on green hats = Total logos - Logos on red hats
How many hats are red, or have logos, or both?
Red hats + Logos on green hats

Answer 4

Can we do a venn diagram?

Answer 5

So total red would be 15 right?
