Determine if the ordered pair (6, 4) is a solution to the inequality
NI
A. Yes, because (6, 4) is above the line
B. No, because (6, 4) is below the line
C. Yes, because (6, 4) is on the line
D. No, because (6, 4) is on the line

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

13.46

step-by-step explanation:

16.80 x .20 = 13.46

multiply then divide

step-by-step explanation:

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
