Tamara gets paid an annual salary of $48,000 and earns 4% commission on all sales she makes. If Tamara wants to make $6,000 this month, how much in sales does she need to have?a. $30,000
b. $50,000
c. $100,000
d. $150,000

Answers

Given that Tamara's annual salary is $48,000 means that his monthly salary is $48,000 / 12 = $4,000. For Tamara to make $6,000 this month, she needs to make an additional $2,000 from commissions in addition to her salary. Given that she earns 4% commision on all sales, let the sale she needs to make to get $2,000 be S, then 4 / 100 x S = 2000 this gives 0.04S = 2000 giving that S = 2000 / 0.04 = 50,000. Therefore, Tamara needs to make a sales of $50,000 to be able to earn $6,000 this month.

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!! I CANNOT RETAKE THIS!!What are the factors of the polynomial function?

Use the rational root theorem to determine the factors.

Answers

Answer: (x - 2)(x + 2)(2x + 1)

Step-by-step explanation:

        q                     p

f(x) = 2x³ + x² - 8x - 4

rational root theorem: (p)/(q) = +/- (1, 2, 4)/(1, 2) so the possible roots are: +/- 1, 2, 4, (1)/(2)

Let's try x = 2

2  |   2     1     -8     -4

   |   ↓     4     10     4

       2     5     2      0   remainder is 0 so (x - 2) is a factor

0 = (x - 2)  (2x² + 5x + 2)

0 = (x - 2)  (x + 2)(2x + 1)
Answer: X - 2 ( X + 2) (2 x + 1)
