Calculating Mural Pricing and Costs

The video tutorial explains a scenario where students create 20 murals to sell at a PTA auction to cover material costs. Initially, each mural needs to be sold for $4 to meet the $80 material cost. However, after three murals are damaged, the remaining 17 murals must be sold at a higher price to cover the same cost. The tutorial guides viewers through calculating the new minimum price per mural, which is approximately $4.71, using basic algebraic methods.
