Tina has a pet sitting business. She charges a flat service fee of $30, plus $15 per day for each animal. If one of her customer
s spent less than $75 on one animal, which of the following inequalities could be used to solve for x, the number of days the customer paid for pet sitting? A.
$15x - $30 < $105
B.
$15x + $30 < $75
C.
$15x < $75
D.
$15x < $105
The answer is B., based on the distributive property (multiply coeffictients, add exponents, change signs because of the negative number being multiplied)
