So you want to find two numbers that add up to -13 and multiply to
40. You can find the factors of 40 and find the pair that adds up to
-13. -8 and -5 multiply to 40 and add up to -13.
<span><span>(x−5)</span><span>(x−8)</span>=<span>x2</span>−13x+40</span>
You can use foil to test it
<span><span>x2</span>+<span>(−8x)</span>+<span>(−5x)</span>+40=<span>x2</span>−13x+40</span>
<span><span>x2</span>−13x+40=<span>x2</span>−13x+</span>
We are given the current market price that is <span>$1,200 and we are asked in the problem to compute the target cost if one wishes to gain a 30% profit. In this case, we have to minimize the cost to achieve the profit desired. Then,
1.3 y = 1200
where y is the target cost
y = $923.08

Answer:
Step-by-step explanation:
Given:
Hairstylist schedule:
1/4 hour to trim a customer's hair
1/6 hour to style the customer's hair
Work per week:
2 × 1/3 hours per day
= 7/3 hours oer day
5 days a week
Hours in a week = 7/3 × 5
= 35/3 hours per week.
A customer must have hair styled and trimmed.
Total number of hours per customer = 1/4 + 1/6
= 5/12 hours per customer.
Therefore, 28 appointments can be nade each week.
Total number of hours per week = 5/12 × number of customers, n
35/3 = 5/12 n
n = 28 customers per week
