Answer:
62.8% OR 0.628
Step-by-step explanation:
11 hours playing video games
11 hours on the Internet
11 + 11 = 22
5 hours of free time each day
7 days in a week
5 x 7 = 35
22/35 hours are spent
That is 0.62857142857 or I just mathmatically rounded to 0.628
0.628 into a fraction is 62.8%
Multiplying the two pieces of the function together:
. This is a quadratic function, and since the coefficient of <em>x</em>² is negative we know it is opening downward and thus has a maximum. We can find the maximum by finding the vertex. First we find the axis of symmetry:
. This tell us there will need to be 3 $5 decreases in price, or a $15 decrease, to maximize the function. $50-$15=$35.
We now plug our 3 in for <em>x</em> in our function:
If they decrease the price their total revenue will be $30,625.
Looking at the function we know that they sell an extra 125 yearbooks for every $5 decrease in price. There were 3 $5 decreases, so 3(125) = 375 extra yearbooks. Add this to the original 500 and we have 375+500=875 yearbooks.
Answer:
Step-by-step explanation:
Given:
Amount deposit P = $2,000
Time t = t year (yearly) = 4t(quarterly)
Rate r = 5% annual = 5/4 = 1.25% (quarterly) = 0.0125
Find:
Amount after t year (Y)
Computation:
A = P[1+r]ⁿ
So,
