Answer:
$43.02
Step-by-step explanation:
In order to solve for the total cost of Sasha's brunch, we multiply the initial price by the decimal form of the given tip percentage and add this result to the initial price. The formula will look like:
initial price + (initial price x tip percentage) = total
Start by identifying what is necessary to plug into the formula. The initial price of the meal was $35.85. The tip percentage is 20%, which can be converted into a decimal by dividing 20 by 100, equaling .20.
Thus:
35.85 + (35.85 x .20) = total
According to the order of operations, otherwise known as PEMDAS, we must solve the equation within the parentheses first, represented by the letter P in this acronym.
35.85 + (7.170)
We can drop the trailing zero in the value within the parentheses because it is not a significant figure. The equation now becomes:
35.85 + 7.17
Finally, perform addition like normal:
43.02
The total cost of Sasha's brunch if she leaves a 20% tip will come out to $43.02, forty-three dollars and two cents.
