Answer:
A. $1852.50
Step-by-step explanation:
Principal amount= P= $3, 900
Rate= r = 19% = 0.19
Time (in years) = t = 2.5
<u>Amount after 2.5 years (A)</u>



Total interest in 2.5 years = A-P = 5752.5 - 3900 = 1852.50
P = price of tickets
8.50p = 42.50
you then divide 8.50 on both sides
8.50p = 42.50
——— ———
8.50 8.50
p = 5
meaning Allison bought 5 tickets in total.
I got 1.5, but I could be wrong.
