Question

Sarah is purchasing pencils to share. Each package has 12 pencils. The equation n = 12p, where n is the total number of pencils and p is the number of packages, can be used to determine the total number of pencils Sarah purchased. Determine which variable is dependent and which is independent. Then, make a table showing the number of pencils purchased for 3–7 packages.

Answer 1

Each package has 12 pencils

total number of pencils Sarah purchased: n = 12p

n = total number of pencils

p = number of packages

n depends on p, because the total number of pencils dependos on how many packages she will buy, so:

independent variable: p

dependent variable: n

╔═══╦══════════╦════╗

║ p ║ n = 12p ║ n ║

║ 3 ║ n = 12*3 ║ 36 ║

Answer 2

Answer and Step-by-step explanation:

Each package has 12 pencils

total number of pencils Sarah purchased: n = 12p

n = total number of pencils

p = number of packages

n depends on p, because the total number of pencils dependos on how many packages she will buy, so:

independent variable: p

dependent variable: n

╔═══╦══════════╦════╗

║ p ║ n = 12p ║ n ║

╠═══╬══════════╬════╣

║ 3 ║ n = 12*3 ║ 36 ║

╠═══╬══════════╬════╣

║ 4 ║ n = 12*4 ║ 48 ║

╠═══╬══════════╬════╣

║ 5 ║ n = 12*5 ║ 60 ║

╠═══╬══════════╬════╣

║ 6 ║ n = 12*6 ║ 72 ║

╠═══╬══════════╬════╣

║ 7 ║ n = 12*7 ║ 84 ║
