Your local bakery charges $6.00 for one dozen of doughnuts. (one dozen is 12 doughnuts). if you purchase any number of doughnuts over one dozen, you will only have to pay $0.40 per doughnut. the total cost of any number of doughnuts is given by the expression below. 6+.40(d-12) which part of the expression represents the number of doughnuts purchased at the discounted rate? a. d b. (d-12) c. 6 d. 40(d-12)

I think it would be B.) (d-12) because that is showing the variable (how many donuts were bought) minus a dozen.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
