1. Let x be the total earnings that Huong needs to make in order to save $396. The equation to represent the situation would be:
0.40x = $396
2. To solve for x, we divide both sides by 0.40:
x = $396 / 0.40
x = $990
Huong will have to earn $990 in total for her savings to equal $396.
3. Let w be the number of weeks it will take for Huong to save $396 by putting aside 40 percent of her weekly salary of $90. The equation to represent the situation would be:
0.40($90)w = $396
4. To solve for w, we first calculate 40 percent of $90:
0.40($90) = $36
Substitute this into the equation:
$36w = $396
Divide both sides by $36:
w = $396 / $36
w = 11
Huong will have to work for 11 weeks to save $396 by putting aside 40 percent of her weekly salary of $90.
