3. The function A(t) = 99t describes the cost of Cell Phone Plan A (in dollars) for t months.
The table shows the cost of Cell Phone Plan B
for t months. Which plan will cost more for 6
months, and which function describes the cost
of Plan B?
t
1
2
3
B(t)
$150
$200
$250
A. Plan B; B(t) = 100t + 50
B. Plan B; B(t) = 50t + 100
C. Plan A; B(t) = 100t + 50
D. Plan A; B(t) = 50t + 100

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

the answer is $42.96

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

-1
