Answer 1

Let T= 5 (since there is 60 mins in 1 hr.)

so 84 shoppers hours = 60 mins

so , 1.4 shoppers per min using given formula with r = 1.4 and T = 5 yields

N = r × t = 1.4 × 5 = 7

Therefore N = 7

Answer 2

Answer:

N = 45

average no. of shoppers = 90

Shoppers per hour = 60

no.of shoppers/ time = 90/60 = 1.5 shoppers per min

r = 1.5

T (time) = 12 mins

So using formula

N = rt = 1.5 × 12 = 18

So to calculate %

=

\frac{45 - 18}{45} \times 100

45

45−18

×100

= 60

hence 60 % less than average no. of shoppers in the orginal store .
