umber of days Doug has shoveled. Then write an expression for the number of
tons Doug has shoveled. X=# days
b)
Three days later, Sid joins Doug, and both shovel together. Write an expression for the num
days Sid has been shoveling in terms of your variable in part a. Then write an expression for the
