Mr. Morton bought a new shed with 156 more square feet of storage than his old shed. Mr. Morton's new shed has 300 square feet of storage. Let \( s \) represent how many square feet of storage Mr. Morton's old shed had. Which equation models the problem? \( s+156=300 \quad s-156=300 \) Solve this equation to find how many square feet of storage Mr. Morton's old shed had. \( \square \) square feet
