The tally chart shows a group of students’ favorite superheroes. How many people prefer Wolverine or Spider-Man?

We’re shown a tally chart. Children were asked to pick their favorite superhero: Wolverine, Superman, Wonder Woman, or Spider-Man. How many children liked Wolverine best? It’s five. When we’re counting tally marks, this is how we show five. One, two, three, four, five. Four students liked Superman best. Four students also picked Wonder Woman. And three students chose Spider-Man.

The question asks, how many people prefer Wolverine or Spider-Man? We know that five students chose Wolverine and three chose Spider-Man. If five students prefer Wolverine and three students prefer Spider-Man, we know that eight students preferred Wolverine or Spider-Man because five and three equals eight. We read the information in the tally chart and used it to help us solve the problem.
