Exclamatory for the phone not sure about the car one
Hello, I believe it is the first one. Hope that helps!
I would say that the decimals equal to 77 is 0.77 as 77 is 77% of 100.
For future reference it would be more beneficial to give options when asking your questions.
A word which means an excess of or an abundance in supply is surplus.
But I think the answer you ware looking for is surfeit, which is also a synonym with the same meaning!
Hope this helps, if you need anymore help or need further explanation just let me know!! :)
