Sounds like a drop shipping business.

Profit = selling price - cost - delivery - expected faults in current batch of microwaves (along with redelivery)
You will need the profit percentage (usually in terms of selling price)

You will need to check the formula for expected value.

The textbook definition of profit is what is left over after all costs have been deducted.
Other than delivery and cost of buying the microwave, you have a certain number of faulty microwaves you expect to have within your batch of 133. The cost entailed with those are the cost of repariing the microwave and the delivery cost on top for sending the repaired microwave to the customer.

Use the number of faulty microwaves in the previous month as a benchmark for figuring out the expected number of microwaves to be faulty.

Of course, if there were that many faulty microwaves in a given batch in real life, I'd question the quality of the merchandise and the manufacturer.

hi so for the cost i did 133x 32= 4256
she pays for the delveery so i assume that goes into her costs so 133 x 7= 931
her sales are 133 x 60= 7980- not assuming any faulty microwaves
if it was 6 out of 80 last month i don't know how to figure out how many there will be with 133 microwaves that's the bit i am stuck on

Have you covered expected value or probabilities in lessons?
It shouldn't be that difficult.

no i haven't but what i did what i put 6/80 as a fraction then found out if one was faulty what chance would it be out of -how many microwaves- so i did 80 divided by 6=13.3 then i did 133/13.3= 10 so 10 out of 133 are faulty idon't know if this is right

It's the long way going about it, and it's a bit inaccurate, but it's right.

hi but what do you mean what bit is right - so the 10 is right??

10 is roughly the right answer for the expected number of faulty microwaves, but that's because you've rounded up 13.33333.... to 13.3
