Answer:
She shouldn't tip at all since that's a ridiculous concept
Step-by-step explanation:
common sense
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>
So five pages of her fiction book in 7 minutes. And she must read thirty pages:
30/5 = 6.
6 * 7 = 42 minutes for the fiction book.
So 2 pages of her history book in seven minutes.
30/2 = 15.
15 * 7 = 105 minutes for the history textbook
Add:
42 + 105 = 147 minutes.
