The art club is selling their handmade jewelry to raise money for new paints and brushes. earrings were sold for $6 a pair and necklaces were sold for $12.50 each. they sold a total of 30 items and made $264.50.

which system of equations best represents the situation above?

note: in all of the choices below, e represents money earned, p represents price, and n represents number of items sold.

a
earrings: e=6(30-n)
necklaces: 264.50-e=12.50*n

b
earrings: e=12.50(30-n)
necklaces: 264.50-e=6*n

c
earrings: e=6(n-30)
necklaces: e-264.50=12.50*n

d
earrings: e=30-n
necklaces: 264.50-e=n

what is the answer?

(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
