Question

you order two servings of Pancakes and a fruit cup. The cost of the fruit cup is one dollar and $1.50. You leave a 15% tip. Your total bill is $11.50. How much does one serving the pancake cost?

Answer 1

one serving of pancake is x dollars and fruit cup is y dollars

(2x+y) * $1.15 = $11.50
y is $1.50
thus,

(2x+1.50) * 1.15 = 11.50

2x+1.50 = 11.50/1.15
2x+1.50 = 10
2x = 8.50
x= $4.25

therefore the cost of one serving of pancakes is $4.25

Hope this helps :P

Answer 2

An equation is formed when two equal expressions. The cost of serving a pancake will cost $4.25.

What is an equation?

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.
