1. mr. xavier took his 18 students and 9 other chaperones to an amusement park. he paid $882 for admission. mrs. yadira took her 11 students and 4 other chaperones to the same amusement park. she paid $489 for admission. which equation should be added to the equation 18s + 9c = 882 to determine s, the amount the amusement park charges for student admission? a. 22s + 10c = 978 b. 11s + 5c = 489 c. 9s + 5c = 441 d. 11s + 4c = 489

Given that number of students taken by Mr. Xavier = 18

Let admission fee per student = $s

Then total charge of students = 18s

Given that number of chaperones taken by Mr. Xavier = 9

Let admission fee per chaperones = $c

Then total charge of chaperones = 9c

Then total fee paid by Mr. Xavier = 18s+9c

which is equal to fee paid $882

So we get equation 18s+9c=882

Same way we can create equation for fee paid by Mrs. Yadira

which is 11s+4c=489

This equation can be added to the previous equation in order to solve for unknown variables s and c.

Hence final answer is D. 11s + 4c = 489

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195
