Carmen punchased n notebook they were 5 dollars each write a equation to represent the total cost c that Carmen paid

c = 5n

Step-by-step explanation:

each notebook is 5 dollars. so we multiply each notebook Carmen buys by 5 to find what she has to pay in total.

it's like if you eat 2 chocolates, and each contain 100 calories, you would be eating 200 calories total. the equation for that scenario would use the same logic:

totalCalories = 100*numberOfChocolates

since 100 is the number of calories in 1 chocolate.
