A dance club plans to buy sweatshirts for its team members. A black sweatshirt costs $18, and a white sweatshirt costs $20. The club plans to spend no more than $230 an buy a total of at least 12 sweatshirts. If x and y represent the number of black and white sweatshirts, respectively, which inequalities represent the situation?

18x+20y≤ 230

Step-by-step explanation:

step one

given data

A black sweatshirt costs $18, and a white sweatshirt costs $20

let x be the number of black and

let y be the number of white sweatshirts

step two:

Also, we are told that the club plans to spend no more than $230

hence the inequality for the situation is

18x+20y≤ 230

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
