Plan How can you solve the problem? You can make a table. List the amount of money you save each day. Remember to double the number each day. Monday $3 Tuesday Wed. Thursday Friday

Solve Monday $3 Tuesday ($3 + $3) $6 Wednesday ($6 + $6) $12 Thursday ($3 + $3) $6 Wednesday ($6 + $6) $12 Thursday ($12 + $12) $24 Friday ($24 + $24) $48

Look Back Does my answer make sense? The numbers were doubled each day, so by Friday I saved $48 dollars.
