Answer:
15% markup
Step-by-step explanation:
5% markup would be $1. Since 20*5% or 20*.05=1
We can multiply it by 3 to find the percent for $3 markup. Which is 15% or 0.15
Answer:
x = 7
Step-by-step explanation:
First, solve by dividing y with x
When x = 6, y = 36
36/6= 6
6(x) = y is your equation.
Now plug in 42 for y
6(x) = 42
Isolate the x. Divide 6 from both sides
(6x)/6 = (42)/6
x = 42/6
x = 7
7 is your answer for x.

Answer:
Step-by-step explanation:
32 - 7(6+12) / 4^2
25 + 18 /4^2
43 / 16
2.6875 when you round it you get 2.7
Answer:
see below
Step-by-step explanation:
If your calculator doesn't have a % key, you can change each of the percentages to a decimal by dividing the numerical value by 100. "%" means "/100".
44% = 44/100 = 0.44 . . . . . . both fractions are read "forty-four hundredths"
Then 44% of 205 = 0.44×205 = 90.2
When you have repetitive calculations like this, a spreadsheet or calculator is handy.
The trigonometry ratio that we shall use to solve the question will be:
tan θ=opposite/adjacent
where:
opposite=8.9 cm
adjacent =x cm
θ=55°
plugging the values and simplifying we obtain:
tan 55=8.9/x
thus
x=8.9/tan55
x=6.23 cm~6.2 cm
