10% for 1 year = $13
10% for 4 years = 13 x 4
= $52
2x+10=y
6+10=16
Choice C (3,16) is correct.
Extremely sorry for this late answer
A = 4 (25 * 25 = 625, 5^4 = 625)
B = 3 (3125 / 25 = 125, 5^3 = 125)
C = 0 because 5(^0) = 1 always
D = ? sorry can't help
C.
The 520 is the new thing added to the equation, which makes it equal to the new weight room's size.
Step-by-step explanation:
<u>Part a</u>
P(x) = 0
150x - x^2 = 0
x(150-x)
x=0,150
Laura should sell 150 pies in order to "break-even" on her sales.
<u>Part b</u>
Because the maximum profit occurs at the vertex of the function,
x = -b/2a = -150/-2 = 75
P(75) = 150 * 75 - 75^2 = 5625
Laura maximizes her profit to $5625 when she sells exactly 75 pies.
