A. Find the percent of change in the number of units sold between 2004 and 2006 and between 2006 and
2008 for each format. Round your answers to the
nearest tenth.

b. Tell whether each percent of change in part a is a
percent of increase or a percent of decrease.

c. Did these trends change from 2004 to 2008?
Explain.

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

y - 25 = 2 ( x - 10 ) should be the answer
