The last time Helen played softball, she hit the ball 15% of the times she was at bat. Based on this information, how many times will Helen hit the ball the next time she plays softball if she is at bat 20 times?

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

Suredude why not right

Tha answers are c. 2 and d. 7.5 ; )
