Answer:
C) Carla is totaling the money made at the student council car wash.
Step-by-step explanation:
In the case of Carla, who is raising money is important to calculate the exact amount of the proceeds, so it is not possible to make approximations.
In the rest of the scenarios, make an approximation as a practical and quick way to calculate the totals.
x^{2} + 13x +36
Answer:
(X+9)(x+4)
Step-by-step explanation:
Find 2 numbers that add to get the middle number and also multiply to get the last number
An equation is formed when two equal expressions. The cost of serving a pancake will cost $4.25.
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that your total bill amount is $11.50. Also, you give a tip of 15% of your bill. Therefore, if the amount of the bill is assumed to be x then the total bill amount can be written as,
Total bill amount = Bill amount + 15% of the bill amount
$11.50 = x + 0.15x
11.50 = 1.15x
x = $11.50 / 1.15
x = $10
Therefore, the bill amount for the food was $10.
The cost of the fruit cup is $1.50, while the order was two servings of Pancakes and a fruit cup. Therefore, if the cost of a serving of pancake is assumed to be 'c'. Then we can write,
Cost of fruitcake + Cost of two pancakes = $10
$1.50 + 2c = $10
2c = $10 - $1.50
2c = $8.5
c = $8.5/2
c = $4.25
Hence, the cost of a serving of pancakes will cost $4.25.
