Question

Mark is buying supplies for his students. He is buying a notebook (n) and a pack of pencils for each of his 25 students. Each pack of pencils costs $1.25. If Mark's total cost is $156.25, which of the following equations can be used to find how much each notebook cost? Select TWO that apply.

Answer 1

Answer:

$5

Step-by-step explanation:

• Note. There are no options to select.

Let the notebook cost x, then Mark spent:

• 25x + 25*1.25 = 156.25
• 25x + 31.25 = 156.25
• 25x = 156.25 - 31.25
• 25x = 125
• x= 125/25
• x= 5

Notebook costs $5
