Let x = Huong’s total earnings.

1) 40% of what number equals $396?
Equation: 0.40x = 396
Solve: x = 396 ÷ 0.40 = 990
So Huong must earn $990 in total.

2) How many weeks if she saves 40% of $90 each week?
She saves 0.40 × 90 = $36 per week. Let w = number of weeks.
Equation: 36w = 396
Solve: w = 396 ÷ 36 = 11
So it will take 11 weeks.
