For this item, any answers that are not whole numbers should be entered as decimals, rounded to the hundredth. marissa's fashions purchases designer boots from a manufacturer for $50.88 per pair. marissa then adds a certain amount to the price of the boots as a markup when she sells them in the store. the total cost for a customer buying the boots at the store is $90.10. this includes a 6.25% sales tax that is added after the markup. the percent of markup before tax is about %, which is a markup of $ per pair of boots.

we'll proceed along the same lines as the previous one.

the cost of the boots is 90.10 and that includes 6.25% sales tax, so if "x" is the 100%, then 90.10 is really the 106.25%, because is including the extra 6.25%.

so if that's the cost of each boot, without tax, then the markup will be 88.8 - 50.88 = 37.92.

if the 100% is 88.8, how much is 37.92 off of it in percentage?

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
