Answer:
53 bagels
Step-by-step explanation:
The number of bagels, y sold is a function of the square of the time (x) plus 4.
Therefore:
[tex]y=x^2+4[/tex]
Number of Hours from 12.00 am to 7:00 am =7
At x=7
The number of bagels sold,
[tex]y=7^2+4\\=49+4\\=53\\[/tex]
The bagel shop sold 53 bagels from 12: 00 am to 7: 00 am.
