Bly sold 29 scarves last month
<em><u>Solution:</u></em>
Let "x" be the number of scarves sold
Bly made 7 more scarves than she sold
Then, number of scarves made = x + 7
Bly makes fleece scarves and sells them for $11 each
Thus for selling "x" scraves , he will get 11x dollars
Total sales revenue = 11x
number of scarves made = x + 7
The supplies cost her $5 per scarf
Therefore, cost for scarves made = 5(x + 7)
Therefore,
profit = Total sales revenue - cost for scarves made
profit = 11x - 5(x + 7)
profit = 11x - 5x - 35
profit = 6x - 35
Last month, Bly had a profit of $139
139 = 6x - 35
6x = 174
x = 29
Thus Bly sold 29 scarves last month
Answer:
JK=7
Step-by-step explanation:
From the line segment, since J is on it ,it means the line segment is
represented as I J K
from this illustration, we can say that the longest part of the line segment is from I to K
this means that, IJ +JK =IK
making JK the subject,
JK= IK - IJ
but from the question, JK=2x-1 , IK=3x+2 and IJ=3x-5
substituting them in the expression,
2x-1 =3x+2 -(3x-5)
solving for x
2x-1 =3x+2-3x+5
2x-1 =0+7
2x-1 =7
2x=1+7
2x=8
dividing through by 2
2x/2 =8/2
x=4
but the question says we should find the numerical value for JK
but from the line segment,
JK=2x-1
but now we know the value of x to be 2
so substituting it in the formula
JK= 2(4)-1
JK=8-1
JK=7
therefore, the numerical value for JK is 7
