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

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

the answer is c.
