The cost of both plans when the cost is the same will be $68.8.
Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's suppose the number of minutes is x
Now,
The total cost of plan A ⇒
25 + 0.14x
The total cost of plan b ⇒
9 + 0.19x
Now, if the total cost is the same
25 + 0.14x = 9 + 0.19x
0.19x - 0.14x = 25 - 9
0.05x = 16
x = 320
Hence "The cost of both plans when the cost is the same will be $68.8".
