So we take 212/8 to get the number of chocolate bars and we get 26.5. David can not sell half a chocolate bar so he must sell 27 chocolate bars.
x = numbers of chocolate bars sell
y = 8x
It cost David $212 to make chocolate bars
Profit:
8x > 212
x > 26.5
David needs to sell at least 27 bars to make a profit.
