Answer:
Step-by-step explanation:"
The electrician charges an initial fee of $42", AND "The electrician charges $22 for every hour worked" is true.
The equation is y=22x+42. The formula is y=mx+b.m is the slope, or is this case, the number of dollars for every "x", which is the number of hours worked. So you have to pay $22 for every hour the electrician works.b is the y-intercept, or the amount it starts with, in this case, you have to pay a fee of $42 even when the electrician worked 0 hours. This is because $42 is the amount it starts with.On a graph, the line will start at (0,42) because that is when you start paying. And then it will increase by 22 for each hour, so the next coordinate would be (1,64).
So for this, we will be using the exponential equation formula, which is y=ab^x, with a = initial value and b = growth/decay. Since the value is increasing, you would add 1 and 0.02(2% in decimal form) together to get 1.02, which will be the b variable. And since we are starting in 2005 with $8 and trying to figure out the value in 2011, 8 will be the a variable and 6 will be the x variable (2011-2005=6)
With this info, our equation will be: y = 8(1.02)^6
Firstly, solve 1.02^6: y = 8(1.12616242)
Next, multiply and your answer will be (rounded to the hundreths): y = $9.01
