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.

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5
