Slope of the given line = 4 slope of the req. line = 4 equation of the line y - y1 = m(x - x1) y + 8 = 4(x - 3) y + 8 = 4x - 12 4x - y - 12 - 8 = 0 4x - y - 20 = 0
Based on the given problem above, here is the solution. Given: Iris's charge: 470 1 1/5 times her fee: additional hourly rate ? = fee for an hourly rate What we need to do first is divide 470 by 7 hours, so 470/7 = 67.143/hour. So Iris's per hour is 67.143 without the additional rate. Now, let's look for the 1 1/5 of 470. 1 1/5 is equal to 1.2. So 470 x 1.2 = 564. To get the total fee of her hourly rate, we add 67.143 and 564, so Iris's hourly rate then is 631.143 or 631.14.
