A store buys 200 shirts at the cost of 1,600$ and sells them at 10$ . What the percent markup

25% markup

Step-by-step explanation:

they bought 200 shirts for 1600, which is 8$ per shirt

if they sell then at 10$ they get 2 dollars profit.

if you do 2/8 you get 25%

Also 1/4 of 8$ is 2$ and that is what your profit is.

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
