Sue started the day with $260 in her bank account. She purchased 15 books that we're all the same price. After she left the store, she had -$10 in her account. How much did each book cost?

$18

Step-by-step explanation:

Since she ended up with -$10 in her account after leaving the store, that means that she spent $270 at the store total.

Since the books were the same price, just divide.

270/15=18

This means that each book cost $18

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17
