For this case, the first thing we must do is define variables.
We have then:
x: number of minutes
y: total cost
We write the algebraic expression that models the problem.
We have then:
Simplifying we have:
Then, by the time the cost is equal to $ 300 we have:
From here, we clear the value of x.
Answer:
an algebraic expression for the problem is:
12+12 is 24, 24+24 is 48, and 48+4 is 52. Hope this helps!
