it would be 9493.8. in 9493.77378844, the first number to the right of the decimal is the tenths place,which is 7, if you round up whats in the hundredths place,which is also 7, the tenths place will go up one. If the number is less than 5,you will not round up. if its 5 or more the number to the left will go up one number.
I hope this helps.
