Final answer:
Elsa will earn $192.40 in commission for selling $5200 worth of furniture.
Step-by-step explanation:
To calculate Elsa's commission, we need to find 3.7% of the total amount of furniture she sells. First, we convert 3.7% to decimal form by dividing it by 100, which gives us 0.037. Then, we multiply 0.037 by $5200 to find Elsa's commission.
0.037 x $5200 = $192.40
Therefore, Elsa will earn $192.40 in commission for selling $5200 worth of furniture.
