The cost of a laptop computer in 2007 was $1,250. In 2009, the price decreased to $1,100.

A) Find the percent decrease in the price of the laptop from 2007 to 2009.

B) Find the percent decrease in the price of the laptop from 2009 to 20010 if the price decreased by $165 in 2010.

PLEASE SHOW WORK!!!

Step-by-step explanation:  1,250+1,100=2,350.

2007+2009=4016

 2007+20010=22010

2010+165=2075

2,350+4016+22010+2075=30451

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week
