I can't solve the problem

14.29 shops

Step-by-step explanation:

Total number of shops:

= 30 + 28 +16 + 14 + 10 + 7 + 3

= 108 shops

Median position = 108/2 = 54

Median is in range where cumulative number of shops is 54.

Range is: More than or equal to 10

Median = Lower limit of median range + range of median range * (median position - cumulative frequency up to median range) / frequency of median range

=  10 + 5 * (108/2 - 30) / 28

= 10 + 4.29

= 14.29 shops

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
