We’ll first find how much she has left as her savings
$490-$396.90= $93.70
Now we’ll go for cross multiplication
100% $490
? $93.70
? = 100 x 93.7/490
? = 19.1 %
So the answer is 19.1% which rounded to the nearest whole number is 19%. The answer is the first option.

Well the volume of dirt she needs to remove is equal to length*width*height=6.2*4.9*0.225=6.8355
Now let's find how many bags she needs.
To solve for this, simply divide room in bags from total room.
6.8355/0.87=7.857
Thus Zoe has barely enough, but enough bags.
-2(y-3)=22
-2y+6=22
-2y=16
y=-8
