Assuming a is 0, b is 1, c is 2, d is 3
a= 2, b= 7, c= 9, d= 2
For this case we have:
Represents the solution of all strict minor numbers to 2.
Represents the solution of all numbers greater than or equal to 2.
The solution set, according to the figure, is given by the union of and 
. Thus, the complete solution is given by all the real numbers.
Answer:
Option D
Multiply the amount with the discount
95 x 0.15 = 14.25
Since it is discount, subtract $14.25 from the total amount: $95
95 - 14.25 = $80.75
B) $80.75 is your answer

Answer:
y=1, y=-2/5
Step-by-step explanation:
$15.81
15% of $20 is $3 so subtract that from $20 and u get $17.
Then 7% of $17 is $1.19 so subtract that from $17 and you get $15.81, which is the amount Lin’s father would pay for the meal in the end.
