Sophie had a 15% off coupon for the book store. The original price of
the book she bought was $14.99. Calculate the discount. What was the sale price?

Answers

｡ₓ ू ₒ ु ˚ Your answer would be 12.75! ˚ ू ₒ ु ₓ｡

⭒❃.✮:▹ Considering 15% of 14.99 is 2.24, we would need to subtract that amount from 14.99.

14.99 - 2.24 = 12.75. ◃:✮.❃⭒

Hope this helps! ♡

The selling price of the book will be equal to $12.74.

What is the percentage?

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Sophie had a 15% off coupon for the book store. The original price of the book she bought was $14.99.

The selling price will be calculated as,

Selling price = 14.99 x ( 100 - 15)%

Selling price = 14.99 x ( 85 / 100 )

Selling price = 14.99 x 0.85

Selling price = $12.74

(-15,-6), (8,3) Find the slope of the line through each pair of points?

Answers

Slope is equal to the change in

y

over the change in

x

, or rise over run.

m = change in y / change in x

The change in

x

is equal to the difference in x-coordinates (also called run), and the change in

y

is equal to the difference in y-coordinates (also called rise).

m = y^2 - y^1 / x^2 x^1

A hotel has a total of 172 rooms. About 58% of the hotel rooms have 2 queen beds in each room and the rest of the rooms have 1 king bed. How many rooms have queen beds?

Answers

Answer:

Step-by-step explanation:

Answer:

Queen rooms: 99.76 but since it is a real world problem round it to the nearest tenth

king rooms: 72

Step-by-step explanation:

172 x 58% or 172 x 0.58= 99.67.

rounded = 100.00

172 - 100 = 72

100= queen rooms
