Answer:
3 dollars
Step-by-step explanation:
Yeah but what is the question?
Cost of Alejandro's food = $12
Tip paid by Alejandro = 20% of his bill = 20% of 12 = 2.4
Cost of Mia's food = $18
Tip paid by Mia = 15% of his bill = 15% of 18 = 2.7
Total Tip Paid = 2.4+2.7 = 5.1
Total Check Amount = 12 + 18 = 30
Total tip paid by Alejandro and Mia is r% of the total check amount.
So, we need to determine what % of 30 is equal to 5.1%
⇒ r% × 30 = 5.1
⇒ r% = 5.1 / 30
⇒ r% = 17%
Hence, r is 17%
How about this:
The book has 712 pages. Ted has already read 408 pages, so he has 304 left to read.
712 - 408 = 304
Any improper fraction would work for this case since they are all greater than 1. For instance 3/2 * 2 would be equal to 3 which is greater than 2.
