Answer:
a: $392.28
b: $112.08
Step-by-step explanation:
The decimal form of 40% is 0.4. Multiply 0.4 by 280.20, and you get 112.08
Because it is a markup, you add this 112.08 to your original price, 280.20
280.20+112.08=392.28
Your answer to letter a is $392.28
The rate of the markup is how much was added, so 112.08
Answer:
The answer is 36 x⁴ y⁴
Step-by-step explanation:
A zero has a "multiplicity", which refers to the number of times that its associated factor appears in the polynomial. For instance, the quadratic (x + 3)(x – 2) has the zeroes x = –3 and x = 2, each occuring once.
Step-by-step explanation:
2×9n=18n
2×-6=-12
52-12+18n= 38 +18n
2×7n=14n
8×2=16
14n+16
38+18n=14n+16
subtract 14n from 14n and 18n
38+4n=16
subtract 38 from 38 and 16
4n=-22
divide each side by 4
n= -5.5
