60 votes are required to change a village parking law. if 9/20 of the 100 people in a village vote to change the law, are there enough votes to change the law?

see explanation

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

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
