You want to divide the cost of the books by the total costs.
308/2800 = 0.11
You then need to convert 0.11 to a percent: 0.11 = 11%
Therefore, 11% of her costs last semester were spent on books.
That’s too much!

Answer:
355.83 yd²
Step-by-step explanation:
A = (B + b)h/2
A = (21.6 yd + 19.3 yd)(17.4 yd)/2
A = 355.83 yd²
Answer: 132 children's tickets and 251 adult tickets were sold.
Step-by-step explanation:
Let x represent the number of children tickets that were sold.
Let y represent the number of adult tickets that were sold.
A total number of 383 tickets were sold. This means that
x + y = 383
Children's tickets cost $4 each and adult tickets cost $6 each. If the total amount for which the tickets were sold is $2034, it means that
4x + 6y = 2034 - - - - - - - - -- -1
Substituting x = 383 - y into equation 1, it becomes
4(383 - y) + 6y = 2034
1532 - 4y + 6y = 2034
- 4y + 6y = 2034 - 1532
2y = 502
y = 502/2
y = 251
x = 383 - y = 383 - 251
x = 132
