The seventh and eighth grade bands held a joint concert. Together there were 188 band members. If the eighth grade band is 3 times as big as the seventh grade band, how big is the eighth grade band?

Respuesta :

take 188 ÷ 4 = 47
I believe 47 members in 7th grade, therefore 47 × 3 = 141 band members in 8th grade.
141 + 47 = 188
