Ella bought balance beam online. It Cost$249plus 29%shipping and handling. What Was The Total Cost?

Work Shown:

29% of 249 = 0.29*249 = 72.21

Shipping and handling is $72.21

This adds onto the original cost to get 249+72.21 = 321.21

A shortcut is to multiply by 1.29 since 1.29 = 1 + 0.29 = 100% + 29%

so, 1.29*249 = 321.21 and we get the same answer

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.

25
