Answer:
$20.49
Step-by-step explanation:
8% = 8/100 = 0.08
Therefore, 8% of 18.97 = 0.08 x 18.97 = 1.5176
So the total price = 18.97 + 1.5176 = 20.4878 = $20.49
Alternatively,
108% = 108/100 = 1.08
18.97 x 1.08 = 20.4878
Answer:
D
Step-by-step explanation:
Since both equations express y in terms of x, equate the right sides
- 2x + 11 = - 3x + 21 ( add 3x to both sides )
x + 11 = 21 ( subtract 11 from both sides )
x = 10
substitute x = 10 into either of the 2 equations for y
y = - 2x + 11 = - 20 + 11 = - 9
solution is (10, - 9) → D
