Section 2: Application 2) Juan is collecting dimes and nickels in a jar. He has collected $22.25 so far.

The relationship between the numbers of dimes (d) and nickels (n), and the amount of money in dollars is represented by the equation 0.10d + 0.05n = 22.25.

Select all the values (d, n) that could be solutions to the equation while also showing the work or evidence of how you know those are solutions

A. (0, 445) B. (223, 21) C. (118, 209) D. (172, 101)

step-by-step explanation:

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
