Answer:
Norton's
Step-by-step explanation:
Suppose that the down payment of Mazzeo's store = 1/3 on all installment purchases
Whereas Norton's depot required 30% down payment on installment purchases.
1/3 is fractional value of 33.33%.
therefore, Norton's Store's down payment rate is lower than that of Mazzeo's store.
I believe the answer is-
a) 80
b) 130
c) 250
(25 -21)/(28 -20) = 4/8 = 1/2
Your probability is 1/2.
16 = 4²
So, by the definition of logarithms
