This is a maximization problem so we apply derivatives here to determine the unknown variables in the problem.
In this problem, we represent x as the number of hats made, and y as the number of Afghans made by Mrs White.
Equation 1 relating to the time it takes to make these is expressed:
7x + 4y = 68
Another equation that represents inequality to the number of hats and Afghans respectively is expressed:
x<= 14
y<=11
the third equation expresses the income from selling these items expressed as
P = 21 x + 9y
we subtitute 1 to 3
P = 9(68-7x)/4 + 21x = 153-15.75x + 21 x = 153 -5.25x
So by trial and errror, x and y should be integers, we get two cases of which x and y should be
1) x = 4 ; y = 10
2) x = 8 ; y = 3
Subsituting to 3, P1 = 174$ while P2is equal to $195, Answer then is 8 hats and 3 Afghans in total.
.45 is just 45/100. divide both numbers by 5 to get 9/20.
Pass = $21 , Souvenir = 2x/3 = $14 , Burger = x/6 =$3.5 .
Answer:
hello your question is incomplete attached below is the missing table
answer = $48700
Step-by-step explanation:
Calculate the total account receivable in each age category
1) not yet due age category
= $4000 + $4000 + $7000
= $15000
2) up to 1 year age category
= $20500 + $7000
= $27500
3) more than 1 year age category
= $6200
therefore the total amount of account receivables = 15000 + 27500 + 6200 = $48700
Answer: a=7 and b=8 so you put them in the places they belong
