No, it is not correct, d has no value so it is 17d. if d did have a value though then d would equal around 4.6
Step-by-step explanation:
To start off with, DF=EG's reason is given, since you stated it was given.
Next, DE+EF = EF+FG's reason is because of the substitution property of equality. Think "if a = c, b = c, then a = b"
Lastly, DE = FG's reason is because of the Subtraction property of equality. If you subtract EF on one side, you must do it on the other side.
10% * $230.00 = $23.00
The discount is $23.00.

Of course, you know that 10% expressed as a decimal is 0.10. Many calculators will calculate percentages directly. If yours doesn't, you can use the decimal equivalent. If you recognize that multiplying by 1/10 simply shifts the decimal point to the left one place, you can do the arithmetic in your head.
