Q. There were 1515 kids at the park. When it began to rain, kk of them went home. Choose the expression that shows the number of kids left at the park.\newlineChoices:\newline(A) 1515\newline(B) 15+k15 + k\newline(C) k15k - 15\newline(D) 15k15 - k
  1. Initial Kids at Park: There were originally 1515 kids at the park. When it started raining, kk kids went home. To find out how many kids are left, we subtract the number of kids who went home from the total number of kids initially present.
  2. Calculate Remaining Kids: The expression for calculating the remaining kids is 15k15 - k. This shows the initial number of kids minus the number who went home.
  3. Check Work with Example: To check our work, let's assume k=5k = 5 (just as an example). Substituting k=5k = 5 into the expression, we get 155=1015 - 5 = 10. This means 1010 kids are left at the park, which makes sense.
