The double number line representing customers who ordered tacos out of 200 is marked from 0 to 80. The percentage of customers who ordered tacos is 40%, calculated as 80/200.
(a) Draw a Double Number Line:
|---------------------|---------------------|
0 80 200
Represent the number of customers who ordered tacos (80) on the double number line.
(b) Percentage of Customers who Ordered Tacos:
To find the percentage, set up a proportion:
![\[ \frac{\text{Number of customers who ordered tacos}}{\text{Total number of customers}} = (80)/(200) \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/ulms1i9ipf9pygl1fuabk0zsqjdarbb91i.png)
Simplify the fraction:
![\[ (2)/(5) \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/qczmy5k0jg72edudlg1hgexetvt29ivxw7.png)
Now, convert the fraction to a percentage:
![\[ (2)/(5) * 100\% = 40\% \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/1pkx0018b1upp1i4yqqikdvabp73kij67g.png)
So, 40% of the customers ordered tacos during lunch.
The double number line, ranging from 0 to 80 out of 200, illustrates that 40% of customers ordered tacos during lunch at the food truck. The percentage was derived by comparing the number of taco orders to the total customers.
