To answer the question, I assume that the given percentage is in terms of volume. The amount of bleach in gallons is the product of the amount of solution x and the decimal equivalent of the percentage. That would give answer equal to 0.70x. The answer is the second choice.
Hrs worked = 9.25 + 8.75 + 9 + 8.25 + 9 = 44.25 hrs. (44.25 - 40 = 4.25 hrs overtime)
<span>40 hrs * $9.32 = $372.80 (Straight time) </span>
<span>$9.32 * 1.5 = $13.98 (Overtime rate) </span>
<span>4.25 (Overtime hrs.) x $13.98 (Overtime rate) = $59.42 (Overtime pay) </span>
<span>$372.80 + $59.42 = $432.22 (Total gross pay)</span>
First find the slope:
m = ( 2 - 1 ) / ( 0 - (-1) ) = 1 / 1 = 1
Set up slope-intercept form:
y = 1·x +2
Now move x and y to the left and leave 2 on the right:
-x + y = 2
This is also equivalent to x - y = -2, so that just depends if you want your x coefficient to be positive or negative.
