The formula for permutation is given as
nPk = n!÷(n-k)!
Where n is the number of objects, k is the is the number of objects we want to chose from.
Solution to the question
15P8 = 15!÷(15-8)!
= 15!÷7!
= 15×14×13×12×11×10×9×8×7×6×5×4×3×2×1÷7×6×5×4×3×2×1
= 259459200

SORRY MADE A MISTAKE WITH THE CALCULATOR I KNEW I MESSED SOMETHING UP
The cost of the meal was $22 so that's the price plus tax and tax is 10% of the price so
cost = price + 0.1*price
cost = 1.1 * price
price = cost / 1.1
price = 22 / 1.1 = <u>20</u>
now we need 20% of that so that's
20 * 0.2 = <u>4</u>
If she's simple-minded enough to tip that would amount to <u>$4</u>
