Respuesta :

Answer:

1080 pies are sold in 4 hours

Profits will exceed $1,000 at 8:22pm

Step-by-step explanation:

First find how many 4 minute periods are in 4 hours.

240 minutes in 4 hours so divide by 4

240/4 =60

Now multiply by 18 to find total orders.

60x18

1080 order in 4 hours

Divide by 18/4 to find order per min

18/4= 4.5

Now if there is an $11 profit for 10 orders then the profit is 1.1 times the order so now you divide 1000 by 1.1.

1000/1.1=909.09

divide by 4.5

909.09/4.5=202

202 minutes=3 hours and 22 minutes

Profits will exceed $1,000 at 8:22pm
