Answer:

Step-by-step explanation:

Amount paid for first 100 watches = (65% of 80) *100

$=\frac{65}{100}*80*100\\\\= 65*80\\= 5200$

Amount paid for next 50 watches = (55% of 80) * 50

$= \frac{55}{100}*80*50\\\\= 55 * 8 * 5\\\\= 2200$

Remaining watches = 280 -(100+ 55)

= 280 - 155 = 125

Amount paid for 125 watches = (45% of 80) *125

$= \frac{45}{100}*80*125\\\\= 45 * 20 * 5\\\\= 4500$

Amount received by the watch maker = 5200 + 2200 + 4500

= £ 11900
