Answer:
$134.40
Step-by-step explanation:
The markup is 28% of 105, or .28(105) = $29.40
Thus the retail price is $105 + $29.40 = $134.40
The parabola opens down, since the 'a' value of the equation is a negative value.
Answer:
a = 1, b = 0 & c = -1;
a = 1, b = 2 & c = 3
Step-by-step explanation:
a = 1, b = 0 & c = -1;
so a + b + c = 1 + 0 + (-1) = 0
&
1 x 0 x (-1) = 0
Other possible answers;
a = 1, b = 2 & c = 3
