Step-by-step explanation:
$100 In 4 stores that 400 but then I did 30 times 5 which is 150 but 150 plus 400 is 550 so I rounded that and I got 525 now this just me I would choose that if I was you right now But I don’t know if I’m correct so ask somebody else to make sure cause I don’t want you to get a bad grade if you have any questions or another way we can figure this out just comment and I’ll reply and try to help

We want to find how much Janice spends on her last purchase.

The correct option here is C, she must have spent $50 on the last store.

Let's see how to get the correct answer:

We know that the average is $30 per store, and we know that she goes to 5 stores, then the total amount spent in the 5 stores is:

5*$30  = $150

Notice that average is just given by the total amount of money she spent divided the number of stores she visited, this does not mean that she spent $30 in each of these stores.

Now, we also know that in the first 4 stores she spents a total of $100.

We want to know how much does she spend on the last store, this will be given by the difference between the total amount and $100, this is:

$150 - $100 = $50

So she must have spent $50 on the last store, meaning that the correct option is C.
