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

(Since it's a gain, we add?)

b.) An electric iron was bought for $150 and sold for a profit 10%. What was the selling price?

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?

Original Price = Unknown (g)

Sale Price (Final Price) = $30

Loss % =

Relating these is the problem I'm having:

g = 45
