The $50 off was like a coupon after you brought all your merchandise to the counter, so we have to add it back in to determine the number of shirts.
$400+$50=$450 original price of shirts
Original price ÷ price per shirt= quantity purchased
$450 ÷ $15/shirt= 30 shirts purchased
Allison bought 30 shirts.
Hope this helps! :)
Just plug in 500 for p, 0.2 for r (because 20% is equivalent to 0.20), and 2 for t:

So, if you start with $500 and charge an interest rate of 20% for 2 years, you will gain $200 to get $700 in total.
