The the s t r i t o n family had a meal catered for a wedding rehearsal dinner the cost of the dinner was $476 they're real 5% sales tax and they were left a 15% tip what was the total cost including the sales tax and the tip

Add 5% to the 15% you get 20%. now multiply 476 by 1.20 to get the total cost

The answer is C, 7.5.

This is because you know that these are the same objects, since it’s asking to find the scale factor. You are able to correlate AB to EF, and that shows a scale UP of 1.5, from 2 to 3. With this scale factor of 1.5, we know that EH will be 1.5 times bigger than AD. So 1.5 x 5 is equal to 7.5.
