Give the step-by-step reasoning process and then the final answer. Teagan saved 200 pennies in her piggy bank. Rex has a mason jar filled with 100 nickels. Toni has 330 dimes stashed inside a giant mug. How much money did the three kids save altogether?
User
Teagan saved 1 cent (.01) x 200 = $2. Rex has 5 cents (.05) x 100 = $5. Toni has 10 cents (.10) x 330 = $33. Together, the three kids saved $2 + $5 + $33 = $40.
The final answer: 40.
