During his vacation, Dalyn rents a small boat from a rental service that charges a flat fee of $40 plus $ 20 per hour (including taxes). The total charge comes to $130, which equation can be used to calculate the number of hours, X, that Dalyn rents the boat?
A 20.x + 40 = 130:4.5 hours
B20(20 + 40) = 130: 4.5 hours
40.2 + 20 = 130, 3.5 hours
D 30(2 + 10) = 90 3.5 hours

im with everythinglos so yeahhhhh

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.

the graph line crosses the x axis at both -6 and -2, so the answer would be the second one.
