Suppose the current cost of gasoline is

$3.48

per gallon. find the current price index number, using the 1975 price of

56.7

cents as the reference value.

the current price index number is

nothing.

(round to one decimal place as needed.)

The current price index number is $604.2.

Step-by-step explanation:

The index value is the ratio between the current value and the reference value, multiplied by 100.

In this problem, we have that:

Current value = $3.48

Reference value: $0.576

Index price = (3.48/0.576)*100 = $604.2.

The current price index number is $604.2.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
