Answer:
Add 12 and 15 to their X value.
Step-by-step explanation:
X = 28, but they could check by adding 12 and 15 to see if it adds to 55.
Answer:
1) $0-22,500.
2) $500.
Step-by-step explanation:
1) A good scale to use for this question would be $0-22,500 at least. You would start with 0 because if you have $0 then you will get no car. And all the way to at least $22,500 because that is the average cost of an SUV at that dealership within 10 years and to go any lower than that would make it inaccurate.
2) 500 would be the best interval to use for this question because 22,500 ends in 500 which means when you count by 500 you will easily get to 22,500 without counting by 1's.

<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>
