A pair of shoes usually sell for $63. If the shoes are 40% off, and a sale tax of 7% is allied to discount cost, what is the total price of the shoes, including tax?round your answer to the nearest penny.

$42

Step-by-step explanation:

40% of $63 is $25.2

$63 - $25.2 = $37.8

How much your paying without tax 37.8

7% of $63 is $4.41.

$37.8 + $4.41 = $42.21

Rounded 42.21 = 42

Im not 100% sure about the rounding but I hope this helps!

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

answer for #1 is c

answer for #2 is d
