1998 CEMC Gauss (Grade 7) Problems/Problem 10


At the waterpark, Bonnie and Wendy decided to race each other down a waterslide. Wendy won by 0.25 seconds. If Bonnie’s time was exactly 7.80 seconds, how long did it take for Wendy to go down the slide?

$\text{(A)}\ 7.8 \qquad \text{(B)}\ 8.05 \qquad \text{(C)}\ 7.55 \qquad \text{(D)}\ 7.15 \qquad \text{(E)}\ 7.5$


Wendy took $7.8 - 0.25 = 7.55$ seconds, so the answer is $\boxed{\text{(C)}}.$
