=2/3 x 4 1/5
Change 4 1/5 to improper fraction
=2/3 x 21/5
Multiply the two numerators together and multiply the two denominators together
= (2*21)/(3*5)
=42/15
Convert back to mixed fraction
= 2 12/15
Simplify by dividing 3 into top & bottom
ANSWER:
= 2 4/5 simplest mixed fraction
Hope this helps! :)

=========================================================
Explanation:
Vertex form is
y = a(x-h)^2 + k
We are told the vertex is (3,-2), so we know (h,k) = (3,-2)
y = a(x-h)^2 + k will update to y = a(x-3)^2 - 2
--------
Then we also know that (x,y) = (4,3) is a point on the parabola. Plug those x and y values into the equation and solve for 'a'
y = a(x-3)^2 - 2
3 = a(4-3)^2 - 2
3 = a(1)^2 - 2
3 = a - 2
3+2 = a
5 = a
a = 5
This is the coefficient of the x^2 term since the standard form is y = ax^2+bx+c.
30% off 25: multiply 25 by .30 to find 30%: 7.5. Now subtract that from the sales price: 25-7.5=17.5
Do the same for store B: .40•30=12. 30-12=18.
So store A is better by $.50 :) hope this helps :)
