I dont know what to do please help

Step-by-step explanation:

Number    Price per     Total            Commission                    Total cost

of Shares  Share                             (At 6% of total)        

100           $16.25          $1625              1625+97.5 = $1722.5      

100           $11.31            $1131              1131+67.86=$1198.86

40             $9.15             $366                366+21.96=$387.96

100           $15.27           $1527            1527+91.62=$1618.62

100           $13.22           $1322           1322+79.32=$1401.32

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.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
