Final answer:
Dan made more money last month and he made $129 more than Mike.
Step-by-step explanation:
To determine who made more money last month, we need to calculate the commission earned by each person. Dan sold 227 bikes at $70 each, so his total sales amount is 227 * $70. To calculate his commission, we multiply his total sales amount by his commission rate of 15%. So Dan's commission would be (227 * $70) * 0.15. Similarly, Mike sold 251 tents at $90 each, so his total sales amount is 251 * $90. Mike's commission would be (251 * $90) * 0.10.
To find out who made more money, we compare the commissions earned by both Dan and Mike. Calculate their commissions using the formulas above. It turns out that Dan made $2383.50 in commission, while Mike made $2254.50 in commission. Therefore, Dan made more money last month.
To find out how much more money Dan made than Mike, subtract Mike's commission from Dan's commission. The difference is $2383.50 - $2254.50 = $129.
