Quick zap sold 5550 apps in the first week of availability. suppose that on average they expect to sell 45 apps per hour. a) write an equation for the number of apps a sold t weeks after the first week of availability. b) if sales continue at this rate, how many hours will it take for the company to sell 100,000 apps?

a. A=7560(t)+5550

work: 45 × 24 × 7 =7650

b. t=12.5

100,000=7650(t)+5500     (subtract)

94450=7650(t)     (divide)

12.493386243     (round)

12.5

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
