Answer:
$87.60
Step-by-step explanation:
Assuming that mary is on a fixed income rate, we can calculate that Mary is making approximately $5.84 per week.
17.50 / 3 = 5.833333.... -> <em>5.84</em>
Now we multiply this number by 15 to get the amount of money she saves over this time.
5.84 * 15 = <em>87.6</em>
<em>So, we can see that Mary has saved $87.60 in 15 weeks.</em>
