Answer:
D) x ≥ 3750
Step-by-step explanation:
For this situation, we begin with our expression, 350+0.12x. Since the salesperson wants to earn at least $800, this means she could earn more as well. This is the symbol greater than or equal to:
350+0.12x ≥ 800
Subtract 350 from each side:
350+0.12x-350 ≥ 800-350
0.12x ≥ 450
Divide both sides by 0.12:
0.12x/0.12 ≥ 450/0.12
x ≥ 3750
Because multiply of these two number get you -32, one of these number must be negative.
And because sum of them are positive, positive number must be larger than that negative number (without minus sign)
So list of possible answers are:
-1, 32; -2, 16; -4, 8
And we can see that
-4+8 = 4
So these two numbers are 8 and -4.
