Autumn is paying for college in monthly installments. the college requests that a $1000 down payment be made. autumn will then continue to pay $500 per month to pay for her tuition. a) write an equation that represents autumn’s payment to her college. b) after 4 months, how much will she have paid?

a. 500 X 12 =

b. 20,000

1067

Step-by-step explanation:

Given that:

Error (E) = 0.03

Confidence interval = 95% = 0.95

Sample size (n) = ((Zα/2) / Error)^2 * p(1 - p)

Since no assumption is given ; p = 0.5

α = 0.95

Z(1-α/2) = 1.96

(1.96 / 0.03)^2 * 0.5(1 - 0.5)

(65.333333)^2 * 0.5(0.5)

4268.4444 * 0.25

= 1067.1111

n = 1067
