Answer: the fourth choice: <span>No, the addition symbol was dropped in the second expression
Justification:
1) The right operation is: </span><span>(4.5m + 7/8) - 9 </span><span>= 4.5m + (7/8 - 9), this is you have to keep the + operator, since you are just grouping the terms in an alternate form.
2) Droping the + operator leads incorrectly to the multiplication of the first term, 4.5m to the terms in parenthesis, instead to the addition, which is what corresponds.
</span>
120 + 90 = 210 points
350 - 210 = 140 OR
351 - 210 = 141 (if it must be more than 350, you need <em>at least </em>351 points total, or 141 more points, to get a grade B)
