Question

If someone could explain this by step please

Answer 1

78-56.94 = 21.06

21.06/78 = 0.27

27 % discount

Answer 2

First, we need to figure out what the question is asking. From the information given, we can see that we need to figure out what times 78 will give us 56.94.
56.94/78 = 0.73, or 73%.
Now that we know this, just subtract 73 from 100.
100-73 = 27
The answer is that he is offering a 27% discount
