Answer:
The amount before the tip is $50.
Step-by-step explanation:
Given : Matt paid $55 at a restaurant. That amount included a 10% tip.
To find : What was the check amount before the tip?
Solution : We have given
Matt paid = $55 .
amount included a 10% tip.
Let the amount before the tip = x.
Tip amount = 10% of x is
[tex]\frac{10 x}{100}[/tex] = 0.1 x .
Tip amount = 0. 1 x
Total amount = x + 0.1x = 55 .
1.1 x = 55.
On dividing both sides by 1.1
x = 50.
So, the amount before the tip is $50.
Therefore, The amount before the tip is $50.
