1. **State the problem:** Jimmy has various bills and coins from raking leaves and a birthday check. He wants to deposit all this money into his savings account, which already has 277.48. We need to find the total amount after the deposit. 2. **Calculate the total from bills:** - 3 twenty-dollar bills: $3 \times 20 = 60$ - 1 ten-dollar bill: $1 \times 10 = 10$ - 2 five-dollar bills: $2 \times 5 = 10$ - 4 one-dollar bills: $4 \times 1 = 4$ Total from bills: $$60 + 10 + 10 + 4 = 84$$ 3. **Add the birthday check:** - Check amount: $25$ Total from bills and check: $$84 + 25 = 109$$ 4. **Calculate the total from coins:** - Pennies: $12 \times 0.01 = 0.12$ - Nickels: $44 \times 0.05 = 2.20$ - Dimes: $19 \times 0.10 = 1.90$ - Quarters: $37 \times 0.25 = 9.25$ Total from coins: $$0.12 + 2.20 + 1.90 + 9.25 = 13.47$$ 5. **Calculate total money to deposit:** $$109 + 13.47 = 122.47$$ 6. **Calculate new savings account balance:** $$277.48 + 122.47 = 399.95$$ **Final answer:** Jimmy will have $399.95 in his savings account after depositing all his money.
