Answer:
EZ
Step-by-step explanation:
A. 15 Percent
B. 40 Percent
Haileys work is correct so B should be the right answer
The slope of this problem is 3/4 same as the rate of change
When you solve, a quadratic formula is set up as ax^2+bx+c so in this scenario a is 1, b is -1 and c is -6.
-(-1)+- √- 1^2-4(1)(-1)/2(1) is
1+/-√1+4/2 equals -2 and 3 making the answer c
