Divide 132 by 8. You will get the quotient of 16 and the remainder of 4. So each row has 16 projects. The remaining 4 projects cannot be filled completely in a row.
The markup is 8%, meaning it costs 8% more. The starting price is 100%. Therefore, the markup is 108% of $12. If we multiply 12 by 108% (1.08), we will get our answer of $12.96
