Answer:
the phone order that will exceed $1000 end at 4+ 3hours 23mins = 7:23 PM
Explanation:
Given the following information for pizza delivery
phone orders : 18 orders in 4 minute.
1080 pies are sold in 4 hours
pizzeria starts taking orders at 4:00 PM
profit made = $11 on 10 orders.
When will phone order profit exceed $1,000?
phone orders : 18 orders in 4 minute.
1080 pies are sold in 4 hours
4.5 orders in 1 minute
profit made = $11 on 10 orders.
profit made = $1.1 on 1 orders.
for $1000 = 909.1 orders
at 910 orders the profit made will be $1001 (which > $1000)
therefore, our calculation of time will be base on 910 orders
18 orders in 4 minute
910 orders = 202.2 approximately 202min (which will be less than $1000)
therefore, we need to increase the order to the next minutes says 203 minutes.
913 orders = (913 * 4)/18 = 202.8mins = 3.38 hours = 3hours 23mins
in conclusion, the phone order will end at 4+ 3hours 23mins = 7:23 pm
