5 people can paint 7 walls in 21 minutes
Therefore, 1 person can paint 7 walls in minutes

The correct answer is somewhere
Assume $1000 at 4.9% semi-annually = <span>$1,049.60
Assume $1000 at 4.8% daily = </span><span> $1,049.17
Let's try a bigger number $50'000 </span>4.9% semi-annually<span> $52,480.01
</span> $50,000 4.8% daily = <span> $52,458.37
