Acab ride from your home to the airport cost $23.47. if you want to tip the cab driver close to 10 percent of the fare, how much should you
tip?
a
b.
c
$0.24
$1
$3

C. $3

Step-by-step explanation:

10% of $23.47 is 2.347. Just move the decimal over to the left one place and round up to get the closes dollar amount. Since the 4 is followed by a 7, which is greater than 5, the closest dollar amount would be $2.35. $2.35 is closer to $3 than it is to $1 so to tip the closest to 10%, you would tip $3.

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
