Noetic Math Challenge
Maggie is celebrating her mom's 37th birthday. After Maggie placed
7 candles on the cake, she realized there weren't enough candles.
She decided to replace some candles on the cake with number 7
candles. If each number 7 candle represents 7 years and each
regular candle represents 1 year, how many regular candles on the
cake should Maggie replace with number 7 candles so that all the
candles on the cake add up to exactly 37 years? ?
