What is the unit rate for Bill's boffo bagel?​
Tema [17]

<u>Given</u>:

Given that the graph of Bill's Boffo Bagel.

We need to determine the unit rate for Bill's Boffo Bagel.

<u>Unit rate:</u>

The unit rate can be determined using the formula,

m=\frac{y_2-y_1}{x_2-x_1}

Let us substitute any two coordinates that the line passes through the points in the graph.

Substituting the coordinates (2,7) and (4,14) in the above formula, we get;

m=\frac{14-7}{4-2}

Simplifying, we get;

m=\frac{7}{2}

m=3.5

Therefore, the unit rate for Bill's Boffo Bagel is $3.5.

Hence, the unit rate is $3.50 for 1 bagel.

Thus, Option b is the correct answer.
