Answer:
Step-by-step explanation:
Amount paid for first 100 watches = (65% of 80) *100
Amount paid for next 50 watches = (55% of 80) * 50
Remaining watches = 280 -(100+ 55)
= 280 - 155 = 125
Amount paid for 125 watches = (45% of 80) *125
Amount received by the watch maker = 5200 + 2200 + 4500
= £ 11900
