Remember you can do anything to an eqution as long as you do it to both sides
easy
first one
flat rate+variable rate=amount paid
flat rate=35
variable=15 times hours, so if h=hours then
and amount paied is 95
35+15h=95 is da equation
if we solve
mins 35 both sides and divide both sides by 15
h=4
2nd one
add 5 to both sides and times 4 both sides
c/4=9
c=36
3rd photo
add 6 to both sides
y+6-6≥12+6
y+0≥18
y≥18
So for the Area you would do Length x width, for a square the length and width are equal so if you take the square root of 1/16 you get 1/4
So look:
1) 20 cm by 20 cm by 6 cm
2) 40 cm by 30 cm by 2 cm
Hope this helps!
Get the gross margin percentage of cost and multiply it to the new unit cost to get maintain the same gross margin percentage of cost.
Units Selling Price : 2.50
Unit Cost - <u>1.00</u>
Profit Margin : 1.50
Gross profit margin % on sales: 1.50 / 2.50 = 0.60 x 100% = 60%
Gross profit margin % on cost : 1.50 / 1.00 = 1.50 x 100% = 150%
If the cost increase by $0.25
Unit cost : 1.00 + 0.25 = 1.25
1.25 * 150% = 1.875 gross margin.
Gross margin + Unit Cost = Unit Price
1.875 + 1.25 = 3.125
Gross margin % on sales : 1.875 / 3.125 = 0.60 x 100% = 60%
Gross margin % on cost : 1.875 / 1.25 = 1.50 x 100% = 150%
Hey there!
Formula for the area of a triangle is (1/2)bh.
Base of this triangle is 5, height is 4.
Image attached.
Plug values into the formula:
A = (1/2)(5)(4)
Simplify.
A = (1/2)(20)
A = 10
Area of the triangle is 10 units².
Hope this helps!
