a$)$ Manooch operates a pizza shop in Tahlequah, Oklahoma. The pizza shop makes one thousand five hundred pizzas per month, the labor productivity is $1\mathrm{.}344$ pizzas per labor hour, each worker works one hundred sixty hours per month. The pizza shop has experienced a twenty five percent increase in demand for its pizzas; however, the pizza shop is too small to accommodate additional ovens to cater to this increased demand. Manooch thinks that by loading the ovens differently he would be able to load more pizzas at a time into the existing ovens $($no other change is required$)$; this approach would involve loading by hand, and hence would require additional worker$($s$).$ How many workers will Manooch need to add?
