-8x-7x=-5x-10
Add or move the -10 to the other side
It becomes: -8+10-7x=-5x
Which then becomes: 2-7x=-5x
Add or move the -7x to the other side
It becomes: 2=-5x+7x
Which then becomes: 2=2x

Bad White [126]

Answer:

$131250

Step-by-step explanation:

Talia's earnings during one year are equal to her base yearly salary ($65000) added to her commission. Now, to know the commission it is necessary to find the 2.65% of her total sales ($2.5 million)

Step 1. Divide the total sales or 2,500,000 by 100 considering this represents the total or 100%

2,500,000 ÷ 100 = 25000

Step 2. Multiply this number by the specific percentage (2.65)

25000 x 2.65 = 66250

Now add the commission and the yearly salary

65000 + 66250 = 131250

Hence, total earnings of Talia were $131250
