Ian is buying bagels for a family gathering. Each bagel costs $1.25. Answer the questions below regarding the relationship between the total cost and the number of bagels purchased.

Question

Answer
Attempt 1 out of 2

The independent variable, x, represents the
number of bagels purchased
, and the dependent variable is the
total cost of the bagels
, because the
total cost of the bagels
depends on the
number of bagels purchased
.
A function relating these variables is N, left parenthesis, x, right parenthesis, equalsN(x)=
.
So N, left parenthesis, 8, right parenthesis, equalsN(8)=
, meaning 88
bagels will cost


dollars
.

Answer 1

The independent variable, \( x \), represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the total cost of the bagels depends on the number of bagels purchased.

A function relating these variables is \( N(x) = 1.25x \), where \( N(x) \) represents the total cost and \( x \) represents the number of bagels.

So, \( N(8) = 1.25 \times 8 = 10 \), meaning 8 bagels will cost $10.

Answer 2

n(8) =???

Answer 3

To calculate \( N(8) \), where \( N(x) = 1.25x \):

\[ N(8) = 1.25 \times 8 = 10 \]

So, \( N(8) = 10 \). This means that 8 bagels will cost $10.
