Your not wrong at all. Your 100% correct. The answer you chose is the correct answer.
Answer: 188 children and 200 adults were admitted
Step-by-step explanation:
Let x represent the number of children that were admitted.
Let y represent the number of adults that were admitted.
On a certain day, 388 people entered the park. It means that
x + y = 388
The admission fee at the amusement park is $2.00 for children and $6.80 for adults. The admission fees collected on that day totaled $1736. It means that
2x + 6.8y = 1736- - - - - - - - - - 1
Substituting x = 388 - y into equation 1, it becomes
2x + 6.8y = 1736
2(388 - y) + 6.8y = 1736
776 - 2y + 6.8y = 1736
- 2y + 6.8y = 1736 - 776
4.8y = 960
y = 960/4.8
y = 200
x = 388 - y = 388 - 200
x = 188
The area of a parallelogram can be obtained by multiplying the length of the base by the height. Although no diagram is given, let us assume values of the base and height that would yield one of the choices as answers. Let us say that parallelogram MATH has the following values:
base = 6 m
height = 11 m
Area = base * height = 6 * 11
Area = 66 m^2
Therefore, the answer is B.
