There are 3414 yellow balloons and there are 1762 more black balloons than yellow balloons. If the balloons will be evenly divided among 10 schools, how many balloons will one school receive? Think carefully first, then make a decision:
Black balloons: 3414 + 1762 = 5176. Total balloons: 3414 + 5176 = 8590. 8590 / 10 = 859. Each school will receive 859 balloons. So, the answer is 859.
