Morgan rewrote the expression 90 plus open paren 10 plus 4 point 8 close paren as open paren 90 plus 10 close paren plus 4 point 8 How will this change the work that is needed to evaluate the expression?

In the rewritten expression, (90 + 10) is grouped together, so find that sum first: 90 + 10 = 100. Then add 4.8 to 100. Therefore, 4.8 is added after finding the sum of 90 and 10, which is choice C.
