I need to get the MATLAB calculation for this but I can't. I past the exact same thing into MATLAB R2016b Editor but it gives me error. Please write your answer and telling what is wrong with the code. What should I add or remove in this code to get the answer and calculations. Please explain step by step this is the first time ever that I am using MATLAB. Thanks

In February 2017, Sheridan Construction signed a contract and
commenced construction on a parking garage. The total contract
price was $90.9 million, and was expected to be completed in July
2021 at a total estimated cost of $82.9 million. Payment by the
customer was to be made in several stages, based on significant
events and dates throughout the construction timeline. The customer
was to have control over the parking garage and was able to make
major changes to the project during the construction process.
Sheridan’s year-end was September 30.
By the end of September, 2017, Sheridan had incurred $12,435,000 in
costs and had invoiced $10,100,000 in progress billings. $9,100,000
of the progress billings had been collected.
By September 30, 2018, Sheridan had incurred $51,415,000 in total
costs and had invoiced $45,200,000 in progress billings, including
the progress billings in 2017. Of the total billings, $30,400,000
in total had been collected. Also, Sheridan reviewed its cost
estimates on the project, and now believed the parking garage would
cost $79.1 million in total to complete.
