Josiah puts a quarter in his piggy bank every day for 24 days. Leah saves 50 cents in an empty pickle jar every day for 20 days. Megan saves twice as much as Leah for 12 days.  How much do the three children save together? Give me reasons, before answering the question
Josiah saves 0.25 x 24 = $6. Leah saves 0.50 x 20 = $10. Megan saves $1 x 12 = $12. Together, the children save $6 + $10 + $12 = $28. So the final answer is 28.
