The number of ushers at a basketball game is directly proportional to number of spectators. If there are 510 spectators at the game, 17 ushers are needed. How many ushers are needed for 1,050 spectators?
Let x be the number of ushers needed for 1,050 spectators.
Since the number of ushers is directly proportional to the number of spectators, we can set up a proportion:
510 spectators / 17 ushers = 1,050 spectators / x ushers
Solving for x, we get:
x = (1,050 * 17) / 510
x = 35
Therefore, 35 ushers are needed for 1,050 spectators.
