Question

Dominique collected 15 fewer pieces of litter than Sara. Sara collected 12 more pieces of litter than Piper. If x = 18, how many pieces of litter did Dominique collect?

Answer 1

Dominique collected 15 pieces of litter.

Step-by-step explanation:

Sara collected 12 more pieces of litter than Piper. So if Piper collected x pieces of litter, Sara collected x + 12 pieces of litter. And Dominique collected 15 fewer pieces of litter than Sara. So if Sara collected x + 12 pieces of litter, Dominique collected (x + 12) - 15 pieces of litter.

Given that x = 18, we can substitute it into the expressions above to find the number of pieces of litter Dominique collected:

Dominique = (18 + 12) - 15 = 30 - 15 = 15 pieces of litter.
