Answer:
It is D
Step-by-step explanation:
Within each coordinate it represents (x,y)
The x moves along the horizontal line and the Y moves along the vertical line.
For example: For (-5,5) move to the left 5 times, then move up 5 times.
A negative X goes to the left and a negative Y goes down.
A positive X moves to the right and a positive Y moves up.
Answer:
- $5000 in the first city
- $4000 in the second city
Step-by-step explanation:
Let x represent the pre-tax hotel charge in the first city in dollars. Then the hotel charge in the second city is x-1000 dollars, and the total tax is ...
... 7.5%·x +5%·(x -1000) = 575
... 12.5%·x = 625 . . . . simplify, add 50
... x = 5000 . . . . . . . . divide by 12.5% (=0.125)
The first-city charge was $5000; the second-city charge was $4000.
5x-8< -18
+8 on both sides
5x< -10
X< -2
15 tickets = $105
105 ÷ 15 = 7
1 ticket costs $7.
$7 x 12 = $84
12 tickets cost $84
Answer: $84 (Answer C)
