<span>Christopher bought a new watch at the store when they were having a 20% off sale.
</span><span>If the regular price of the watch was $48, what did Chris have to pay after the discount was applied?
Let w represent the cost of the watch. Then the discounted price would be (1.00-0.20)($48) = 0.8($48) = $38.40 (answer)</span>
6.12% compounded monthly equals 0.0612/12, or 0.0051 added monthly. So, $3500 invested for 4-1/2 years is:
3500 x (1.0051)^(48+6)=1.3161x3500=$4606.48

So basically you just want to find the LCM of the denominators shown, or 2 and 3.
So in this case, you could use the most inefficient method, or listing the multiples out:
2 : 2, 4, 6
3: 3, 6, 9
And as you can see, the first multiple that matches is 6. So your answer would be B, 6.
