Raven needs new winter boots. Both Shoe Town and LaceUp shoe stores carry the boots she wants to buy. The boots are regularly priced $85.95, but both stores are running sales.
Shoe Town has the boots marked down 15%. LaceUp has the boots marked down 10%, plus
Raven has a $5 coupon she can use on the boots after the mark down is applied.
Raven's friend, Becca, tells Raven there is an online shoe store called Run, Don't Walk that has
the boots she wants for only $71.99. If Raven buys the boots in a local store, she will have to pay
7.16% sales tax on her purchase. If Raven buys the boots online, she won't have to pay sales tax,
but she will have to pay $6.50 for shipping.

Raven should buy the boots at LaceUp since total cost is lower ($77.54)

Step-by-step explanation:

price of the boots at Shoe Town:

[$85.95 x (1 - 15%)] x (1 + 7.16%) = $73.06 x 1.0716 = $78.29

price of the boots at LaceUp:

{[$85.95 x (1 - 10%)] - $5} x (1 + 7.16%) = ($77.36 - $5) x 1.0716 = $72.36 x 1.0716 = $77.54

price of the boots at Run, Don't Walk (online store):

$71.99 + $6.50 = $78.49

if im undersanding the question correctly, its organized from 10

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
