let's call the number of adults a and the number of children c.
so the total adults plus the total children equals 40 or a+c=40 or c=40-a
also we know that 8a+5c=272
substituting c's value in the 1st equation into the 2nd equation we get
8a+5(40-a)=272---->lets distribute that left side---->8a+200-5a=272
now let's combine like terms on either side of the equals sign.
3a=72 a=24
so we have highlight%2824-adults%29
and c=40-a(24)=highlight%2816-children%29
Position vector R = < 4,0,1>
(given point)
normal vector n = < 3,-1,9>
equation:
n(r-R) = 0
3(x-4) - y + 9(z-1) = 0
Answer: 70 - 40 = 30
