Step-by-step explanation:
Write formulas for the question.


Then use substitution.




So number of $3 tickets sold is 230. But they ask for the tickets bought in advance (i.e. the tickets sold for $2). Use substitution again.

Answer:
First city: $5,500
Second city: $5,000
Step-by-step explanation:
Let's define x as the hotel price in the first city and y the hotel price in the second city. We can start with this equation:
y = x - 500 (The hotel before tax in the 2nd city was $500 lower than in the 1st.)
Then we can say
0.065x + 0.045y = 582.50 (the sum of the tax amounts were $582.50)
We place the value of y from the first equation in the second equation:
0.065x + 0.045 (x - 500) = 582.50
0.065x + 0.045x - 22.50 = 582.50 (simplifying and adding 22.5 on each side)...
0.11x = 605
x = 5,500
The cost of the first hotel was $5,500
Thus, the cost of the second hotel was $5,000 (x - 500)
Answer:
, where d= distance that Kiran walks in t minutes.
Step-by-step explanation:
Given: Kiran walked at a constant speed.
He walked 1 mile in 15 minutes.
The, distance walked by Kiran in 1 minute =
mile
The distance that Kiran walks in t minutes =
miles
If d= distance that Kiran walks in t minutes
The required equation: 
Answer:

Step-by-step explanation:
1) Add 6 to both sides.

2) Simplify 21 + 6 to 27.

3) Divide both sides by 9.

4) Simplify 27/9 to 3.
