A resturant bill for a group of people comes to a total of $125 . The amount included an %8 of sales tax and a 20% tip both based on foo what is the value for f

Answer 1

The price of food was $97.66

Step-by-step explanation:

Let x be the price of the food

If x is the price, then

Sales tax = 8% = 0.08x

Tip = 20% = 0.2x

Then the equation will be:

$x+0.08x+0.2x = 125\\1.28x = 125$

Dividing both sides by 1.28

$\frac{1.28x}{1.28} = \frac{125}{1.28}\\x = 97.66$

The price of food was $97.66
