Question

\c\ stands for the __________. a circle b cost what is the equation? a c = 1.25t + 18 b c = -1.25t + 18 how much are you charged if you use 4 therms of gas? a $21 b $22 c $23

Explanation:

Step1: Identify what C represents

In a cost - related context, C usually stands for cost.

Step2: Select the equation

Without more context about the relationship between C and t, we assume a positive - slope linear relationship for a cost function where cost increases with the amount of something (t). So $C = 1.25t+18$ is more likely.

Step3: Calculate the cost when t = 4

Substitute t = 4 into the equation $C = 1.25t + 18$.
$C=1.25\times4 + 18$
$C = 5+18$
$C=23$

Answer:

1. B. cost
2. A. $C = 1.25t + 18$
3. C. $\$23$
