15 x 1.59 = 23.85
Her order is between 20 euros and 34.99 euros. Therefore, she gets 2.5% discount.
2.5 x 23.85/ 100 = 0.60
That means she gets approximately 60 cents off her order.
Answer:
Nadia ordered 15 packs so without the discount she will spend 23.85 pound so she will have a discount of 2.5% of the total and you have to do 23.85:100=0,2385
0,2385x2,5=0,596
So she gets a discount of 0,596
