Mr. Smith can bring 6 bags on his trip to Puerto Rico.
Here's how to calculate it:
First, calculate how many bags Mr. Smith can bring per dollar:
1.5 bags / $52.50 = 0.0286 bags per dollar (rounded to the nearest ten-thousandth)
Next, divide the cost of his flight by the rate of bags per dollar:
$262.50 x 0.0286 = 5.99 bags (rounded to two decimal places)
Since Mr. Smith can't bring a fraction of a bag, we round down to the nearest whole number. Therefore, Mr. Smith can bring 6 bags on his trip to Puerto Rico.
