Question

Tony spent $60.54 and bought 3 packs of notebooks and a calculator. How much does a pack of notebooks cost if a calculator costs $45.87? Need equation such as 3(x+45.87)=60.54 but one that works.

Answer 1

14.76

Explanation:

just subtract

Answer 2

Let the price of a notebook = X.

Multiply the cost of a notebook by the quantity, so you get 3x.

Add that to the price of a calculator to get the total spent:

60.54 = 45.87 + 3x

Now solve for x:

Subtract the cost of the calculator from both sides:

3x = 14.67

Divide both sides by 3:

x = 14.67 / 3

x = 4.89

A notebook cost $4.89
