Question

let b equal the price of a bowl of plain phở and let n equal the price of...

1. what does the bar model represent?

complete the statement.

1. the price of a plain bowl plus the price

of 3 extra ingredients equals $ 13.

1. find possible values of b and n.

b = 8
n = |

Explanation:

Step1: Set up the equation

From the bar model: $b + 3n = 13$

Step2: Substitute given $b=8$

$8 + 3n = 13$

Step3: Isolate the term with $n$

$3n = 13 - 8$
$3n = 5$

Step4: Solve for $n$

$n = \frac{5}{3} \approx 1.67$
(Note: If we assume whole dollar values, we can also use other valid pairs. For example, if $b=7$, $n=2$; but using the given $b=8$, we calculate the corresponding $n$.)

Answer:

$b=8$, $n=\frac{5}{3}$ (or approximately $\$1.67$)
