Answer:
D
Step-by-step explanation:
Step-by-step explanation:
2^(2x) - 5(2^x) = -4
(2^x)^2 - 5(2^x) = -4
Substitute 2^x = z --> x = ln(z)/ln(2)
z^2 - 5z = -4
z^2 - 5z + 4 = 0
(z - 1)(z - 4) = 0
z = 1 --> x = ln(1)/ln(2) = 0
z = 4 --> x = ln(4)/ln(2) = 2

As a result of the price increase, an additional $188.50 was made.
The first step here is to find out the increased revenue that was earned on each bag of popcorn:
<em>= New price - old price </em>
= 3.75 - 3.10
= $0.65
The concession stand sold 290 units so the increased amount that was earned was:
<em>= Incremental revenue x Number of units sold </em>
= 0.65 x 290
= $188.50
In conclusion, an additional $188.50 was made.

Given:
Number of times Jenna feeds her cat = 2
Cat food each time 
Number of days = 5
Number of cans she bought = 8
