<span>Let number of experienced crew = X
Let number of novice crew = Y
Number of rooms experienced crew can prep = 6X
Number of rooms experienced crew can paint = 2X
Number of rooms novice crew can prep = 2Y
Number of rooms novice crew can paint = 2Y
Number of rooms to be prepped per week = 12
Number of rooms to be painted per week = 8
So, we have
Equation 1 - For Prepping
6X + 2Y = 12
Equation 2 - For Painting
2X + 2Y = 8 or 2Y = 8 - 2X
Replacing the value of 2Y from equation 2 in equation 1, we have
6X + (8 - 2X) = 12
Simplifying the equation we get
4X + 8 = 12
4X = 12 -8
4X = 4
X = 4/4
X = 1
Replacing the value of X in Equation 1, we get
6 * 1 + 2Y = 12
2Y = 12 - 6
2Y = 6
Y = 6/2
Y = 3
Total cost per week = 1 * 1000 + 3 * 750 = 1000 + 2250 = 3250
So, to optimize costs, John would need 1 experienced crew and 3 novice crews at a total cost of $3250 per week.</span>
Notice the picture below
in a rectangle, all angles are 90 degrees and the diagonals are equal
meaning the diagonals bisect each other, they cut in equal halves
so. those two sides are equal, and thus they make up an isosceles triangle
on the sides
if those two sides are equal, the angles they make on the other side are equal
so if angle D is 55 degrees, angle A is 55 degrees
and the missing angle is 180 - (55 + 55) or 70
that's just the left-side
now, angle "x" on the right side, is a vertical angle of that angle on the left,
and vertical angles are equal, thus x = 70
