Answer:
358
Step-by-step explanation:
f(x) = 3x² - 5
f(-11) = 3(-11)² - 5
f(-11) = 3(121) - 5
f(-11) = 363 - 5
f(-11) = 358
Answer:
Step-by-step explanation:
Let m be the cost of meal in dollars.
We have been given that the tax on meal at the restaurant is 5% of meal, so the cost of meal after tax will be m plus 5% of m. We can represent this information in an equation as:
We are told that Alice decides to leave a tip of 20% of the cost of the meal plus the tax. This means that tip will be 20% of cost of meal after tax.
The total cost of meal will be equal to the cost of meal after tax plus amount paid by Alice as the tip.
Therefore, the expression represents the total amount of Alice's bill in dollars.
