Answer:
a.) her loss is 5 dollars
b.) her profit is 10 dollars
c.) she should sell them for $0.15
Your answer is y = -1/2 and y = 2
To solve this quadratic we first need to subtract 2 from both sides to set it equal to 0, which gives us 2y² - 3y - 2 = 0
Then we just need to factorise it:
2y² - 3y - 2 = 0
(2y + 1)(y - 2) = 0
Now we can set each bracket equal to 0 and solve for y:
2y + 1 = 0
2y = -1
y = -1/2
y - 2 = 0
y = 2

Answer:
Dive 2: -9 37/40 feet
Dive 3: -12 1/20 feet
Step-by-step explanation:
To solve this, we subtract 2 1/8 from -7.8 twice. First, convert -7.8 to a mixed number, that gets us -7 8/10. Now, we find the LCM of 8 and 10. That is 40. Now, we multiply 1/8 by 5/5 to get 5/40. Now, we multiply 8/10 by 4/4 to get 32/40. Now, we subtract 2 5/40 from -7 32/40. This gets us -9 37/40. That means Dive 2 was -9 37/40 feet. Now, we subtract 2 5/40 from -9 37/40. That gets us -12 2/40. We can simplify that to -12 1/20. That means Dive 3 was -12 1/20 feet.
