If it costs Melissa $8.20 to make a pie, how much should she charge for a pie? Round your answer to the nearest cent if necessary.

$10.20 Or $16.40

Step-by-step explanation:

If it cost $8.20 to make a pie you would have to sell it for ATLEAST $10.20 To make a good profit and continue with making pies. (Rule of thumb is you normally want to make Twice the price to continue to sell the goods.)

(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
