Answer:

Step-by-step explanation:
Here, x represents the number of tickets and y represents the number of T-shirts.
As per the statement:
Each ticket costs $25, and souvenir T-shirts are $12 each
⇒Total cost of ticket = 25x and Total cost for T-shirt = 12y
It is also given that there is a $4 service fee for the entire purchase.

Since, she has $130
⇒
Therefore, an inequality could you use to answer the problem is, 
The plane speed in still air is the average of the two speeds: 430 miles/hour.
The wind speed is half the difference of the two speeds: 20 miles/hour.
Well for what I understood...
Let's say...
10 Pigs in total... Horses is 2 times more than pigs so
20 Horses in total... Cow is 4 times more than horses so
80 Cows in total...
The numbers are just examples of what I sort of understood.
The reciprocal of 3/8 would be 8/3 (basically reversing the numbers).
When dividing fractions, you can just multiply the first fraction by the reciprocal of the second fraction instead of dividing by the second fraction.
3/4 ÷ 3/8
= 3/4 × 8/3
Simplifying gives us the final answer:
= 2
Let me know if you need any clarifications, thanks!
I believe the answer the answer is 5.1 b
