Question

a class voted for either rollerblading, swimming, or biking as their favorite summer activity. if rollerblading got 19% percent of the vote and swimming got 31%, what percentage of the class voted for biking?

Answer 1

50

Step-by-step explanation: I think this is the answer because you need to add 19 and 31 and every percent goes to 100% 19 + 31 = 50 and 19 + 31 + 50 = 100 so 50% voted for biking. Hope this helps.
