Answer:

<u>B. </u>a + c = 216

5a + 3c = 902

Step-by-step explanation: This is the correct answer, because a represents adults and c represents children, so a + c = 216 and 216 represents the total number of people that the money was collected from. So, that would be correct for the first part of the system of equations. Next, 5a represents $5 for each adult, and 3c represents $3 for each child. While, 902 represents the total number of money collected at the park. Therefore the answer a + c = 216 5a+ 3c = 902 is the correct system of equations answer. Hope this helps ^-^.

Answer:

Step-by-step explanation:

Total Number of Students =300

Percentage who had cats, n(C) = 40%

Percentage who had both cats and dogs , $n(C \cap D)$ = 12%

Percentage who had neither cats nor dogs, $n(C \cup D)'$ =45%

Now:

Universal Set, $U = n(C)+n(D)-n(C \cap D)+n(C \cup D)'$

$100 = 40 + n(D)-12+45\\n(D)=100-73\\$Percentage of those who own dogs =27\%$

Therefore:

Number of Students who had dogs

=27% of 300

=81
