Asightseeing boat charges $5 for children and $8 for adults. on its first trop of the day, it collected $439 for 71 paying passengers. how many children and how many adults were there?

if 71 paying passengers are all children, they should pay 5* 71= $355 in total.

$439 is paid so adults pay $439-$355 = $84 more than money paid by same number of children.

each adult pays $8-$5=$3 more than each child

so there are $84/$3= 28adults

and 71-28= 43 children

two? xd

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024
