Answer:

y=3x-11

Step-by-step explanation:

(2,-5) (3,-2)

\frac{x_{1}-x_{2}  }{y_{1}-y_{2}  }\\\\

\frac{2_{1}-3_{2}  }{-5_{1}--2_{2}  }\\

= \frac{3}{1}

= 3

y=3x+b

-5=3(2)+b

-5=6+b

-11=b

A café or for senior citizens a 15% discount off it's regular price of $8.95 for the dinner buffet. What percent of the regular
denis23 [38]

Answer:

Price for Senior Citizen = $7.61

Percent of the regular price = 85% off original

Step-by-step explanation:

Regular Price is $8.95

Seniors get 15% off of that. So, first we need to find 15% of 8.95 and then subtract it from 8.95.

To get percentage of a number, we first convert the percentage to decimal (by dividing by 100) and then multiply it with the number.

15% = 15/100 = 0.15

Fifteen Percent of 8.95 is:

0.15 * 8.95 = $1.3425

Senior Citizen Price = 8.95 - 1.3425 = $7.6075

Rounded to nearest cent = $7.61

How much is this as a percentage of original?

Simple, it is 15% off of the regular price, so this price is 100 - 15 = 85% of original price
