Answer:
The amount of white fabric to coloured fabric as a ratio is 20:11
Step-by-step explanation:
We are given that For each 11 mm of colored fabric Nick uses to make his curtains, he also uses 2 cm of white fabric.
Length of colored fabric = 11 mm
Length of White fabric = 2 cm
1 cm = 10 mm
2 cm = 20 mm
So, length of white fabric = 20 mm
So, Ratio of the amount of white fabric to coloured fabric = 
Hence the amount of white fabric to coloured fabric as a ratio is 20:11
Answer:
Gross profit formula= 3x
x= number of units sold
Step-by-step explanation:
Giving the following information:
Unitary variable cost= $2
Selling price per unit= $5
<u>To calculate the profit earned, we need to use the unitary contribution margin formula</u>. The contribution margin is a product's price minus all associated variable costs (sales- variable costs), resulting in the incremental profit earned for each unit sold.
Unitary contribution margin= 5 - 2 = 3
<u>Now, the profit formula:</u>
Gross profit formula= number of units*unitary contribution margin
Gross profit formula= 3x
x= number of units sold
8x -2y + x+x
simply combine like terms
8x+ x + x= 10x
therefore
10x-2y is equivalent
