$34 is a proper 20% tip on a $171.81 dinner. Move the decimal point twice to the left, then multiply that twice.
Parallel lines have the same slope, so the new line will have the same slope as does the given line (which you have not yet given us!). If the given line has slope m = 5, then
y-2 = 5(x-[-8]), or y-2 = 5(x+8).
alternatively, y = 2 + 5x + 40, or y = 5x + 42
Please go back, find the slope of the given line, and re-do this problem, reflecting the value of the given slope.
To get the answer, you will just use this operation: Division.
Let's divide it. 81 ÷ 13.5 = 6.
So, the answer is
Ben earns $6 per hour at the fun station.
First find the amount of the difference between the original price and the current price:
$10,600 - $7,400 = $3,200
Divide the difference by the original price:
3200 / 7400 = 0.4324 = 43.2% increase.
