First find the weekly cost of the first employee: $20/hour * 40 hours/week = $<<20*40=800>>800/week
Then find the hourly cost of the second employee after the government subsidy: $22/hour - $6/hour = $<<22-6=16>>16/hour
Then find the weekly cost of the second employee: $16/hour * 40 hours/week = $<<16*40=640>>640/week
Then subtract the smaller weekly cost from the bigger weekly cost to find the difference: $800/week - $640/week = $<<800-640=160>>160/week
