Agallery owner purchased a very old painting for $3,000. the painting sells at a 325% increase in price. what is the retail price of the painting?

If the owner sold the painting for a 10% increase in price, its retail price would be (1 + 0.1)*($3000) = 1.1*($3000) = $3300.

By the same logic, a 325% increase in price would be (1 + 3.25)*($3000) = 4.25*($3000) = $12,750 retail price. Remember that 100% is equal to 1.00 if written as a decimal, so 325% is written as 3.25. So, multiply 3000 (original price) by 3.25 to get the new retail price.

The answer would be £9750

you do it by doing 3000x3=9000
then you do 3000÷2=1500
then do 1500÷2=750 which is the extra 25%
so now you have the 325% (9000+750=9750)
