Formula for markup
sales price = original price × ( 1 + rate )
So in this case it would be...
sp = $32 × ( 1 + .80 )
$32 × ( 1.80 )
sp = $57.60
formula for discount ( if you need it )
sales price = original price × ( 1 - rate )
Just remember that the rate is the percentage ( to convert to a percentage to a decimal just move the decimal two places to the left )
Answer:
Ummm use Microsoft math calculator
The rational roots of the polynomial given in the question are -4/5 and 3/4.
Given-
Given polynomial function is,

The given polynomial function has the four-degree equation in which the greatest power of the variable is four. Suppose one root of <em>x </em>is 1 to solve it further. So one factor is,

Rewrite the given equation,





On the factor above equation, we get.

Answer:
x-int: 2
y-int: -2
Step-by-step explanation:
