Since Doug’s brother has double the amount of Doug we can just multiply the amount Doug has by 2.
$3,215*2 = $6,430
Answer:
22
74
Step-by-step explanation:
A three digit number would be 294. You could do 200+90+4
At the end of each year, the amount is (1 + 11%) = 1.11 times the amount at the beginning of the year. When that multiplier is applied 5 times, the result is
$30 * 1.11^5 ≈ $50.55
