Answer:
Prachi was 5 kilometers east of her home when she began driving farther east at 70 kilometers per hour.
Let f(n) be Prachi's distance from her home at the beginning of the nth hour of her drive.
f is an arithmetic sequence.
Write an explicit formula for the sequence.
f(n) = 70n + 5

Answer:
price of a computer that she could afford R 9230.769
Step-by-step explanation:
Given data
amount pay = R500 per month = 500 × 24 = R 12000 total pay
time period =24 months = 24 /12 = 2 years
rate = 15 % per annum
to find out
price of a computer that she could afford
Solution
we know formula
Amount Paid = Principal × (1+(RT/100))
put value principal pay and R and T and we get
principal = Amount / (1+(RT/100))
principal = 1200 / (1+(15 ×2 )/100))
principal = 9230.769
price of a computer that she could afford R 9230.769

Cost of 1 pack of trading cards = xTotal packs purchased = 10Cost of 10 packs before discount (A) = 10 * xDiscount percentage = 20 %Discount amount per pack = (20/100) * xDiscount amount for 10 packs (B) = (20/100) * x * 10Cost of 10 packs after discount is (A) - (B) = (10 * x) - ((20/100) * x * 10)Simplifying, we get x * (10 - 200/100) = x * (10 - 2) = x * 8 = 8 * xCost of shipping = $3.99Total cost of 10 packs of trading cards after discount and including cost of shipping can be represented by the algebraic expression 8 * x + 3.99 or 8x + 3.99
