Question
A man bought 4 cups of coffee and left a $7 tip. A woman bought 8 cups of coffee and only left a $2 tip. If they paid the same amount, how much was each cup of coffee?
The correct answer is: $1.25.
- Hint:
○ Solve the equation.
○ Take terms with cofficient at one side and without cofficient at another side.
- Step by step explanation:
○ Given:
A man bought 4 cups of coffee and left a $7 tip.
A woman bought 8 cups of coffee and only left a $2 tip.
Amount paid by both is same.
○ Step 1:
Let the price of 1 cup of coffee be x.
So, in case of man,
Total amount paid = 4x + 7 { %7 is tip }
In case of women,
Total amount paid = 8x + 2 { %2 is tip }
○ Step 2:
○ As amount paid by both of them is same.
∴ 4x + 7 = 8x + 2
7 - 2 = 8x - 4x
5 = 4x
x =
x = 1.25
- Final Answer:
Hence, each cup of coffee cost $1.25.

The x + 2 = 6 x+2=6x, plus, 2, equals 6 contains a variable. We call this type of equation with a variable an algebraic equation. Finding the variable value that will result in a true equation is typically our aim when solving an algebraic equation.
¶Variables or constants are the two types of measurable quantities. A variable is a quantity with a varying value, and the constant value is nothing but a constant.
¶Steps to writing Variable Equation
1) Identify the variables that represent the unknowns.
2) Convert the issue into variable expressions in algebra.
3) Determine the variables' values to solve the equations for their true values.
