How many shots does he shoot? ** He shoots 200*4=<<200*4=800>>800 shots per week
How many arrows can he recover? ** He can recover 800*.2=<<800*.2=160>>160 of those arrows
How many arrows does he use? ** So he uses 800-160=<<800-160=640>>640 arrows a week
How much does he spend for arrows a week? ** The cost for those arrows would come out to 640*5.5=$<<640*5.5=3520>>3520 per week
How much does his team pay for arrows? ** His team pays for 3520*.7=$<<3520*.7=2464>>2464 of that
How much does he spend for arrows a week? ** So he has to pay 3520-2464=$<<3520-2464=1056>>1056 per week for arrows
