here it goes
for the first 1000 the percentage is 0.5 where the credit card company will pay 5 $
for the next 1000-3000$ the percentage is 1.0 where the credit card company will pay pay for 2000$ only as it has paid for first 1000$
which is 20 $
for the next 3000-6000$ the percentage is 1.5 where the credit card company will pay pay for 3000$ only as it has paid for first 3000$
which is 45 $
for the next 6000-10000$ the percentage is 2.0 where the credit card company will pay pay for 4000$ only as it has paid for first 6000$
which is 80 $
so now totally
it is 5+20+45+80=150$
