My question is: Since the 40th president launched his reelection campaign today, he has raised $10,000 in campaign funds. His friends raised 40% of this amount and his family raised 30% of the remaining amount. The rest of the funds are from his own savings for the election. How much did he save for the presidency? Your thoughts:
The total amount of money raised from friends contribution is 40 / 100 * $10000 = $4000. Minus his friend's contribution, the 40th president has raised $10000 - $4000 = $6000. The family raised 30 / 100 * $6000 = $1800. If the family raised $1800, the savings the 40th president had for the campaign is $6000 - $1800 = $4200. The final answer: 4200.
