Matt paid $55 at a restaurant. that amount included a 10% tip. what was the check amount before the tip? a. $40 b. $43 c. $45 d. $50 e. $52

For this case we propose a rule of three:

$ 50 -------------> 100%

x -----------------> 10%

Where the variable "x" represents the amount of the tip.

So, the tip was 5 dollars.

If we subtract that amount to what Matt paid at the restaurant we will have the amount of the check before the tip.
