Answer:
Cost of the meal is $37.86 .
Step-by-step explanation:
As given
Teresa's restaurant bill comes to $29.99 before tax.
If the sales tax is 6.25% and she tips the waiter 20% .
6.25% is written in the decimal form.
[tex]= \frac{6.25}{100}[/tex]
= 0.0625
Sales tax price = 0.0625 × Restaurant bill
= 0.0625 × 29.99
= $ 1.87
20% is written in the decimal form .
[tex]= \frac{20}{100}[/tex]
= 0.20
Waiter tip = 0.20 × 29.99
= $5.998
Total cost of the meal = Restaurant bill + Sales tax price + Waiter tip
Putting all the values in the formula
= $ 29.99 + $1.87 + $5.998
= $ 37.86 (Approx)
Therefore the cost of the meal is $37.86 .
