A bracelet was marked up $50 from cost, which amounts to a 20% increase. Find the original cost of the bracelet

40

Step-by-step explanation:

20% times 50 = 10 thats ten less cuz it asks for the original i think

Original cost was $250

Step-by-step explanation:

let x be the original cost

20 = 50/x x 100

20x = 50x 100

20x = 5000

x= 5000/20

x = 250

oof

step-by-step explanation:

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.
