Mark and jennie are bowling jennie’s score is double mark’s score. if the sum of their score is 135 l, find each person’s score by writing out an equation answer

Jennie has 90 points and Mark has 45.

Step-by-step explanation:

I'm not gonna explain, but I will show my every step :D

J: Jennie

M: Mark

J = 2M

J + M = 135

2M + M = 135

3M = 135

M = 45

J = 2M

M = 45

2 * 45 = 90

J = 90

(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.
