A price increases 7% due to inflation and is then reduced 10% for a sale. Express the final price as a function of the original price, p.

f(p)=?

Thank you for the opportunity to help you with your question!

increases 7% due to inflation

=(7 /100)*p

then total will be

(7 /100)*p+p

= 107 p /100

then reduced 10% for a sale

(10/100) 107 p /100

=1070p/10000

=107p/1000

so final price

= 107 p /100 - reduced 10%

=107 p /100 - 107p/1000

= 107 p ( (1/100) -(1/1000))

= 107 p ( 900/100000)

=107 p( 9 / 1000)

= 963 p /1000............................ANSWER

=0.963 p...................................ANSWER

final price as a function of the original price, p.

f(p) = 963 p /1000

= 0.963 p
