Idon’t know how to do this! this is due tomorrow

140%

Step-by-step explanation:

Okay, first we need to figure out how much a single shirt originally cost, so we divide the total cost by the number of items.

1,800 / 300 = 6

So each shirt was originally six dollars. Now, we need to find out what percent 10 is of 6. To do this, we divide 10 by 6, then multiply the result by 100 to convert from decimal to percentage.

10 / 6 = 1.4

1.4 * 100 = 140

And there we have our answer. Hope this helps!
