Mary has saved $17.50 in the past 3 weeks. at this rate , how much will she save in 15 weeks ?

$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 -> 5.84

Now we multiply this number by 15 to get the amount of money she saves over this time.

5.84 * 15 = 87.6

So, we can see that Mary has saved $87.60 in 15 weeks.
