DeWayne says that 60% more than 50 is 80. Tationna says that 60% more than 50 is 30. Who is right? What mistake did the other person make?

Step-by-step explanation:

The culprit here is the word more. More means that the number they finally get must be larger than 50. So Tationna is incorrect. She made the mistake of thinking that the 60% represented multiplication. She was taking 60% of 50. She was not taking 60% more.

DeWayne has the right answer.

60% of 50 = 60/100 * 50 = 30 as Tationna said.

But that must be added onto 50

50 + 30 = 80

Dewayne is right.

Step-by-step explanation:

Dewayne:

.60 * 50 + 50 = 80

30 + 50 = 80

80 = 80

correct

Tationna

.60 * 50 = 30

She found 60 percent of 50

not 60 percent more

more means add
