the inequality is:
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:
the median is the middle value when a data set is ordered from least to greatest

taxable income = $31000
as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.
so, the tax to be paid by him = 12% of 31000
= 0.12 * 31000 [12% converted to decimal as 0.12]
