David has been tasked with tracking the number of bagels sold (y) at freddy's 24-hour bagel shop from 12: 00 am (*= 0) to 12: 00

mafiozo [28]

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:

$y=x^2+4$

Number of Hours from 12.00 am to 7:00 am =7

At x=7

The number of bagels sold,

$y=7^2+4\\=49+4\\=53\\$

The bagel shop sold 53 bagels from 12: 00 am to 7: 00 am.

15% of 90 hours<br> 15% of 90 hours

Blizzard [7]

Answer:

15 percent of 90 hours = 13.5 hours

What is 15% of 90?

Y is 15% of 90

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 15% * 90

Converting percent to decimal:

p = 15%/100 = 0.15

Y = 0.15 * 90

Y = 13.5
