Huong wants to buy a bicycle that costs $396. She is about to start a new job and
decides to put 40 percent of her earnings aside to save for the bicycle.
2. Solve the equation. How much will Huong have to earn so that her savings will
equal $396?
Let x be the amount Huong needs to earn in order to save 40% of it for the bicycle.
The amount she will save is 0.4x. We want this savings amount to equal $396.
Therefore, we can write the equation:
0.4x = 396
Now, we solve for x:
x = 396 / 0.4
x = 990
Huong will need to earn $990 in order to save 40% of it for the bicycle.
