Positive × positive = positive

Negative × positive = negative

negative × negative = positive.

So in your problem,
5 × -5 = -25

5 (3x - 5) =
15x - 25

Distribute.

5(3x - 5)
5*3x - 5*5
15x - 25

Jason is paid 500 per month plus a commission of 4% of the first 2500 of his sales, and 6% of his sales over 2500. last month hi

Deffense [45]

Begin by subtracting 2500. 22600-2500=20100. Multiply 2500 by .4. 2500×.4=1000
Now, multilply the other number we found by .6. 20100×.6=12060. Add the two numbers, and the original 500 for Jason's gross pay for the month.
500+1000+12060=13,560
Jason's gross pay for the month is $13560.
