Meg paid 9 for 2 tuna sandwiches. at the same rate, how much does meg pay for 8 tuna sandwiches?

Hey You!

I assume Meg paid 9 dollars for 2 tuna sandwhiches.

9 × 4 = 36

(We multiply by 4 and not 8 because she paid that much for every 2 sandwhiches).

Meg pays $36 for 8 tuna sandwiches.

Divide 9 by 2 to give you the price. This will give you $4.50 for each tuna sandwich.
Multiply $4.50 by 8 and this will give you $36.
Hope this helps!! ^v^

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2
