Harry is making cookies he needs one and 3/4 cup of flour for one batch but he wants to make one and a half batches right an equation that can be used to find how many cups of flour Harry will need.

Step-by-step explanation:

1¾ cup/batch

1½ batches × 1¾ cup/batch = 1½×1¾ cups = 2⅝ cups

(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.
