Casey has 5 shirts, 3 skirts, and 2 blazers. what are all the possible combinations?

Step-by-step explanation:

Casey wears shirt, skirt and blazer.

Casey has to choose shirt among the shirts available to her.So,the number of ways she can choose a shirt is .

Casey has to choose skirt among the skirts available to her.So,the number of ways she can choose a skirt is .

Casey has to choose blazer between the blazers available to her.So,the number of ways she can choose a blazer is .

The total number of possible combinations is the product of number of ways she can choose a shirt,number of ways she can choose a skirt and number of ways she can choose a blazer.

So,the total combinations are

In 1990, a total of $514 billion was spent on food and drinks in a particular country. In 2003, the total spent was $904 billion.

(a)

Find the equation of the exponential function that can be used to model the total T spent (in billions of dollars) on food and drinks in this country as a function of the number of years t since 1990. (Round your decimal value to four decimal places.)

T = answer a

(b)

Use your model to predict the amount spent (in billions of dollars) in 2000. (Round your answer to the nearest integer.)

answer b billion dollars

(c)

What is your prediction for the total sales of food and drink (in billions of dollars) in 2018? (Round your answer to the nearest integer.)

answer c billion dollars

(d)

Estimate when the total sales will reach $2 trillion if this exponential trend continues. (Round your answer to two decimal places.)
