At a breakfast buffet, 45% of people choose coffee for their beverage while 25% choose juice. also, 15% choose both coffee and juice. what percentage of people prefer neither coffee or juice? express your answer as percent.

45+15+25=85
100-85=15
15% of people prefer neither coffee or juice

If 45% of people chose coffee and 25% of people chose juice, but 15% of people chose both, then we’d have to subtract 15% from both amounts to find the percentage of people who chose that specific drink.

45-15=30%
25-15=10%

Now add those two together to get how many people prefer coffee or juice. 30+10=40%. If 40% out of 100% of people prefer coffee or orange juice, then the remaining percent of people must not prefer either of them.

100-40=60%.

Therefore, 60% of people prefer neither coffee nor juice.
