Question

each of the 26 and students and Carrie's class chose either drums or horns to play during music class. If 4 more students chose drums than horns, how many choose each

Answer 1

Okay, so here's the equation:
n + (n + 4) = 26
2n = 22
n = 11
So 11 people have horns, but 15 people have drums.
