Margaret wants to buy 10 books. Six of them cost $12.50 each and the rest cost $26.35 each. If she only has $150, how much is she short?

$30.4

Step-by-step explanation:

6x12.50=75

4x26.35=105.4

75+105.4=180.4

150-180.4=-30.4

30.4 dollars

Step-by-step explanation:

Total Cost of six books = 12.50 * 6

                                        = 75

Total Cost of the remaining 4 books = 26.35 * 4

                                                             = 105.4

total cost of 10 books = 75 + 105.4

                                   = 180.4

Difference in cost of the books and the money she has = 150 - 180.4

                                                                                            = - 30.4

Therefore she is short of 30.4 dollars

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
