Question

MEDAL
To maximize profit, when should the store be opened (what hours) and when should it be closed?

Grocery sales
6-7am $40
7-8 80
8-9 120
9-12 400
12-3pm 600
3-4 200
4-5 60
5-6 120
12-1 40

The cost of groceries sold averages 70% of sales. It costs $22/hr to keep the store open.

Answer 1

I tried multiplying the $40 by .7
but that is within making a profit...so it should just keep the same hours?

Answer 2

yum yum!!!

Can't help. Sorry. I don't understand the question. hihihihi :(

Answer 6

I will attempt to help you. So what exactly do you want to know

Answer 7

What hours it is more profitable to keep the store open?
So $22 is a negative value; and the sales for each time period are positive values.

Answer 8

You need to find 70% of 22

Answer 9

To do that you need to multiply

Answer 10

Why? I don't see the connection

Answer 11

You have to use the numbers to create a proportion of your own and make your own connection

Answer 12

No i'm not guess I have a little experience with these problems. I have got them wrong before so now I know how to do them because I have gotten help

Answer 13

I've done up to Calculus II. I know how to do simple multiplication.
.7*22 = 15.4

Answer 14

I just don't get why we're doing that

Answer 15

I think 15.4 would be your answer but you might want to double check

Answer 16

Did that help a little

Answer 17

What?! A simple number is not the answer!
What HOURS it is more profitable to keep the store open?

Answer 18

Answer 19
