Astereo salesperson earns a salary of $1,900 per month, plus commission of 4% sales. the salesperson wants to maintain a monthly income of at least $2,200. how much must the saesperson sell each month?

The salesperson must sell 7500 items to maintain a salary of $2,200.

Step-by-step explanation:

We know that the stereo salesperson earns $1,900 per month and a commission of 4% sales.

So to find out how much must the salesperson much sell each month to maintain a monthly income of $2,200, we will use the following formula:

Income = salary + (0.04) × sales

2200 = 1900 + (0.04) × sales

300 = (0.04) sales

sales = 300/0.04

sales = 7500

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
