For starters, create an equation to show David's earnings. We can do this using Danielle's as a basis, which is set up as y=(# of hours)x+(bonus). This gives us y=12x+80. Now, as we need both their ys to be equal, we just set both equations equal to each other, making 15x+50=12x+80. Now, we solve for x, starting with 15x+50=12x+80, subtracting 12x from both sides to get 3x+50=80, subtracting 50 from both sides to get 3x=30, and dividing three from both sides to get x=10. To check, we just plug in our answer to both equations and see if the ys match up. With Danielle's equation, we get y=15(10)+50=150+50=200 and with David's equation, we get y=12(10)+80=120+80=200, proving that our answer is correct.
Answer:
17 is 35 degrees and 18 is 43 degrees
7 9/11 = 7.81 with a line over the 81 because it is repeating
15/720 = 0.020
7.58
7.812
least to greatest : 15/720, 7.58 , 7.812 , 7 9/11
Days attended = 174
% attendance = 174/182 * 100 = 95.60%
