Question

Explanation help needed please on the following:
A typical customer as a local supermarket spends approx. $75 at checkout,
The store keeps 4 registers open, and each handles 12 cust per hr
Estimate the amount of money the store receives in 1 hour
is this not 75*12*4?
thanks in advance

Answer 1

A few assumptions here. $75 is the AVERAGE each customer spends.
All registers have a long line of people.
Then in 1 hour: 12 * 4 customers
And 12 * 4 * 75 dollars per hour is what the store will make.

Answer 2

my pre test quiz I answered was 3,600 according to correct answer it should have been $3200

Answer 3

see why I am confused? :)

Answer 4

Not sure how with the given numbers one can arrive at 3200. Is the problem reproduced exactly here? Some info may be missing.

Answer 5

will edit above as per question

Answer 6

not sure what ^^^^ means.

Answer 7

3200 / 4 = 800.
Neither 12 nor 75 will divide evenly into 800.
10 customers per hour and $80 average spending will work. And there are other combinations. Bit with the given numbers the answer is 3600.
