Start by putting the inequality in the form


ax+c>d

in this case c wil be how much he has sold, and d will be how much he needs to sell, and a is the price for the bar.

it would look like this


2.5x+40>175

solve it like a regular equation


\begin{gathered} 2.5x>175-40 \\ 2.5x>135 \\ x>(134)/(2.5) \\ x>54 \end{gathered}

He will have to sell over 54 bars to win the prize.
