A sofa regularly rells for $800. The sale price is $600
sveta [45]

Because the sofa usually sells for $800, we know that's 100% of the price.

100% = $800

Let's find 1%.

1% = $800/100

1% = $8

Next, multiply $8 by 75 to find the percent of the sofas price when it's $600.

75% = $600

We now know that $600 is 75% of the sofas original price.

100% - 75% = 25%

The percent of decrease I'm the sofas sale price is 25%.

Hope I got that right, the question was worded a little strangley so I wasn't quite sure what you were asking :)

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.
