From 1995 to 2002, the total fuel consumption T (in billions of gallons) by cars in the US and the US population P (in millions) can be modeled by: T = -0.003x^3 - 0.02x^2 + 1.3x + 68 and P = 3x + 267 where x is the number of years since 1995. Write a function for the average amount of fuel consumed by each person from 1995 to 2002.

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
