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

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
