Morgan rewrote the expression 90 + (10 + 4.8) as (90 + 10) + 4.8. How will this change the work that is needed to evaluate the expression?
4.8 is now multiplied by 90 and 10.
4.8 is now added to 10 before adding 90.
4.8 is now added after finding the sum of 90 and 10.
4.8 is now added to both 90 and 10.
