The data represented on the plot

A stem and leaf plot presented as:

a | b c d

is interpreted as: ab, ac, ad

Using the above as a guide, the data represented on the plot are:

0,5, 11,15,26,45,46,46,46,52,60,71,84,87

(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.

114 plus 113 times 2 and 114 times 3
