## What changes, if any, would you suggest as an outside investor to its business model?

1. Consider some changes and sensitivity analysis. What changes, if any, would you suggest as an outside investor to its business model? What are the risks? What are the implications of these changes? Here this may involve qualitative aspects and “what would you want to know” from an inside the firm perspective.
2.

Use a discount rate of 20% (late stage venture/ IPO tech SaaS company). Consider a range of exit multiples after 3-5 years (15/20/25 times EBITDA).

### Design a rectangular pre-stressed beam section (on allowable stress basis) that supports a live load of 2.5 k/ft on a span of 30 ft. Pre-stress losses = 22%. fc 6000 psi, ftt = -208 psi, fct = 2880 psi, fcs = 3600 psi, fts = -465 psi.
