Yeah, i think the way i would approach this problem is to make a table.
00:04
So with time and whatever the amount is, it doesn't really matter.
00:09
But what does matter is it doubles every week.
00:15
And they tell you that t is in days.
00:18
So what you have to do is think about, okay, if i skip down to seven days, this 1500 amount will double to 3 ,000.
00:28
And if you did another seven days, you know, to get down to 14, that 3 ,000 will double to 6 ,000.
00:36
So as you look at the multiple choice, i don't know if it's obvious to you, but the base, if you're doubling, i'll double check the direction, say doubles.
00:47
Yep.
00:48
If you're doubling, you need to multiply by two.
00:54
Otherwise, my table would have been wrong.
00:56
So as you look at a few options and you tried the, amount, well, first of all, if you're multiplying by two, that needs to be the base...
