y x 0.8 = 80% of y, so do it in reverse. In this case, y = 1600, so 1600/0.8 = 2000
Edit: Keep in mind 1600 is 80% of Regular Price
Answer:
A
Step-by-step explanation:
The graph crosses the x- axis at 2 points, thus has 2 real and distinct roots
Then the discriminant is positive
• If b² - 4ac > 0 then 2 real and distinct roots
<span>2* 25.6 ( 1 - .8^9 ) / (1 - .8) + 32 = 253.6 meters</span>
Part A = 85$
Part B = He pays 25$ a month.
