Answer:

100

Explanation:

The sum of n terms of a geometric series with first term a1 and common ratio r is ...

Sn = a1×(r^n -1)/(r -1)

Here, we have ...

Sn = 1258, r = 1.05, n = 10, so the value of a1 is ...

a1 = Sn(r -1)/(r^n -1) = 1258(1.05 -1)/(1.05^10 -1) ≈ 100

The number of shoppers at the mall the first day was 100.
