12 people plus herself is 13 people. So 13.75(13)=178.75.
So, $178.75 for all tickets. But... I might be wrong.
Step-by-step explanation:
The slopes of perpindicular lines must be negative reciprocals of each other -- while -4 and 4 are negative to each other, the negative recipricocal for -4 is 1/4 and -1/4 for 4.
The slopes of parallel lines must be the same, so these are not parallel.
Answer:

Step-by-step explanation:
Answer:
a. 440
b. 100
c. 1800
d. 320
Step-by-step explanation:
a. $7000 is 3000 +4000 so this falls in two pay ranges.
0.04(3000) + 0.08(4000) = 120+320 = $440
b. $2500 is lower than 300 so it falls in only one pay range.
0.04(2500) = $100
c. 12,000 is greater than both 3000 and 8000 so this falls in the last pay range.
0.15(12000) = $1800
d. $5500 is 3000+2500 so this falls in two pay ranges.
0.04(3000) + 0.08(2500) = 120+200 = $320
