Answer: the final mass of the solid is 176 grams.
Step-by-step explanation:
The "change" between two quantities, one initial Qi and one final Qf is defined as:
Change = Qf - Qi.
In this case, the quantity is mass, and we know that the initial mass is 260 grams.
And we also know that the change is -84 grams.
Then we have the equation:
Qf - 260 g = -84g
Qf = -84g + 260g = 176g
So the final mass of the solid is 176 grams.

so 102% = 30396
100% (original) = 30396/102*100 =29800
Her salary was $29800 before the rise
So 55% is really 55/100
You take 100 - 55 to find how much Mr. Williams drove
100 - 55 = 45
So Mr. Williams drove 45/100 of the miles
Simplified is 9/20 of the miles
