You dont need the percentage of tip. to calculate the bill, divide 100 by 15, then multiply that number by 1.65, you will get the total of the bill afer tax. if you add 1.65 to the total you get the total after tax and tip
Answer:
Step-by-step explanation:
If all 21 coins were dimes, she'd have $2.10. But she has 90 more cents than that. Now for each coin that's a quarter, not a dime, she has 15 cents more. 90/15= 6. So there are 6 quarters, and 21-6 = 15 dimes.
Now we do it backwards to see if it's right. 6 quarters is $1.50, 15 dimes is $1.50, add those together and you get $3. So it's right. 6 quarters, 15 dimes.
I think the answer is 12.6 extra gigabytes because:
20 - 51.50 = 31.50
31.50 / 2.50 = 12.6
