Fluid Mechanics HW How pressure in a tank affects exit velocity of a fluid

[fluidmech]

I'm just a bit lost on how to find the change in pressure. I've posted a picture of my work thus far.

Can't read what you wrote but you seem to be on the right track, using Bernoulli.

I said I was lost and didn't know what to do next..

Could you provide a legible description of the problem. Also your effort at solving.
