QUESTION 5 of 10: To keep your start-up costs low, you decide to hire two salespeople on commission. They have a base salary of $30,000 and receive 6% of all sales in commission. If first year sales are $500,000, what is your total cost for the two salespeople?
a) $80,000
b) $90,000
c) $100,000
d) $110,000
Submit

B. $90000

Explanation:

30000+30000 = 60000

60000 + 30000 (6% commission of 500000) = 90000

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
