They're correct...
Hi,
I'm not sure of these and need them checked, kindly. Alternatives would be appreciated also :-)
a.) A man sold a car for $22 000 and gained 10% on his money. How much did he pay for the car?
M => Amount paid for car

I got this one after trial and error. My answer just coincides with the given. I don't see the reason for multiplying 1.1 by 150.
c.) In a sale the price of a pair of shoes was reduced by . The sale price was $30. What was the original price?

Sale Price (Final Price) = $30
Loss % =
Relating these is the problem I'm having:
g = 45
