Michael is an avid reader, his generous grandparents gave him money for his birthday, and he decided to spend at most $150 on books. barnes and noble is running a special: all paperback books are $8.00 and hard back books are $12.00. michael wants to purchase at least 12 books.

write a system of inequalities to represent the situation.

The system of inequality to represent the situation is

p + h 12  

8 p + 12 h = 150

Step-by-step explanation:

Given as :

Total money to be spend on books = $150

The cost of each paperback book = $8

The cost of each hard back book = $12

The total number of books to be purchased = 12

Let The number of paperback books = p

Let The number of hard back books = h

According to question

Total number of books to be purchased =  number of paperback book + number of hard back book

i.e p + h 12            ...........A

Again

Total money to be spend on books =  number of paperback books × cost of each paperback book  +  number of hard back books × cost of each hard back book

i.e p × $8 + h × $12 = $150

Or, 8 p + 12 h = 150         .........B

So, The system of inequality to represent the situation =

p + h 12     and  8 p + 12 h = 150

Hence, The system of inequality to represent the situation is

p + h 12 and  8 p + 12 h = 150  . Answer

hey i’m new i won’t be answering any questions now bye peeps see you next time

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
