B) Division

When dividing the 3x=9 you need to leave x on its own therefore you decide 3x by 3 to cancel out the multiplication. Than what you do to one side you do to the other so 9/3 = 3 leaving the equation answer: x=3

Feliz [49]

Answer:

$1,008 weekly,  $52,416 annually

Step-by-step explanation:

14% of $7200 is 7200 multiplied by .14 (% is decimal multiplied by 100)

.14 of 7200 = 1008

Since you specified the year, I'm going to assume that you need the annual salary based on the weekly salary that she gets from commissions.

$1008 per week, 52 weeks in a year

52 * 1008 = $52416, her commission in 2011
