Solve the literal equation for x s=2r+3x

s=2r+3x

Move 2r to the other side. Sign changes from +2r to -2r.

s-2r=2r-2r+3x

s-2r=3x

Divide by 3 for both sides

s/3-2r/3=3/3x

x=s/3-2r/3

x=s/3-2r/3

you should pay $0.88

what is the image?

(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.
