Angelica bought a new car at a cost of 22,000. the car's value decreases exponentially at the same rate each year and one year later the car's value was 18,480. what is the common ratio?

We are given cost of new car purchased = $22,000.

Car value is decreasing exponentially.

Car value after 1 year = 18,480.

In order to find the common ratio, we need to divide first year value of the car by initial purchased value.

Therefore, common ratio = 18,480/22,000.

Now, we need to convert 18,480/22,000 into simplest fraction.

Dividing top and bottom by 880 we get,

= 21/25.

we don't have enough info to solve this

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
