Awriter earns $10.50 for each page that he writes. if he works 8.5 hours and writes 12 pages each day on average, which of these proportions can be used to calculate his average hourly wage, w?

Each day he'll earn: $10.50 x 12 = $126.00
And since he works 8.5 hours, his average hourly wage is:
$126.00/8.5 = approx $14.82/hour
