Using proportions, it is found that she would save $900 in a year.
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
She spends $150 a month on clothing and accessories, hence, if she saves half of that, the amount saved in a month is:
0.5 x 150 = $75.
In a year, this amount will add up to:
75 x 12 = $900.
