I need help understanding how to solve this problem any other problem like this.

Lower      Upper       Frequency

1                6                       2

7               12                      4

13              18                      7

19             24                      1

25             30                     4

Step-by-step explanation:

We sort the given data to get: 1,4,8,8,9,10,13,14,15,15,15,16,18,24,25,25,27,29

The range is 29-1=28

Class width=28/5=5.6

We round up to get 6

The lowest value is 1. Our lower class limits are:

1

7

13

19

25

The upper class limits are:

6

12

18

24

30

Now our frequency table is:

Amount         |           Frequency

1-6                                2

7-12                               4

13-18                               7

19-24                               1

25-30                              4

look up a corrdinate plane and do what the thingy says and boom

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
