All you have to do is divide.
332.50/17.50= 19
to check your answer you have to figure out know much money David gets paid each day.
there are 7 days in a week so your going to divide 7 by the amount earned each week: 17.50/7=2.5
to see if you got it correct you're going to multiply, 2.5x7=17.50.
and then multiply the amount paid each week by 19 which gives you the total estimate of 332,50$, 17.5x 19=332.50
