+414 37% of the people in a park are adults. The rest are girls and boys in the ratio 3:4. There are 80 more adults than girls. How many people are there in the park?(help people)
+128475 37% are adults...then, 63% aren't.....and the girl/boy ratio is 3:4.....so 27% are girls and 36% are boys....and we know that.....
.37T = .27T + 80 where T is the total number of people subtract .27T from both sides....
.10T = 80 divide both sides by .10
T = 800 total people
Check
37% of 800 = 296
27% of 800 = 216
And (296 - 216) = 80
