Answer 1

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

$\begin{gathered} 2.5x>175-40 \\ 2.5x>135 \\ x>\frac{134}{2.5} \\ x>54 \end{gathered}$

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