here are 88 swimmers in a meet. 34 swimmers are wearing goggles. 1/3 of boys wear goggles. 3/7 of girls wear goggles. How many girls wear goggles? How many boys wear goggles?

Answer 1

B+G= 88

B/3 + 3G/7 = 34 multiply by 21

7B + 9G = 21(34)=714

7B +7G = 7(88)=616

subtract to get

2G = 98

G = 49

B=39

B/3 = 13 boys wore goggles

3G/7 = 21 girls wore goggles
