We have the original price P and it will increase a rate r%, we can express is as

[tex]P+P\cdot r[/tex]

As we can see, P is the original price and P*r is what's going to be added to the original price, we can even simplify it to

[tex]P(1+r)[/tex]

That's a generic expression to find it, so here we have P = 153 and r = 19% = 0.19, then

[tex]\begin{gathered} P(1+r)=153(1+0.19) \\ \\ 153(1+0.19)=153\cdot1.19 \\ \\ 153\cdot1.19=182.07 \end{gathered}[/tex]

The price will be $182.07
