lisa made a long-distance telephone call to her friend Jane. the cost was $.42 for the fist minute and $.19 for each additional minute. what was the total length of the call if it cost $2.89
Taylor, Nellie, Patrice -- I've showed you how to solve many problems. Now it's your turn.
I'll be glad to check your answer.
well ms sue i got 64 im not sure can you show me
How did you get 64 minutes?
To find the total length of the call, we need to determine the number of minutes Lisa spoke with her friend Jane.
Let's denote the total length of the call in minutes as 'x'.
The cost of the first minute is $0.42, and for each additional minute, the cost is $0.19. This means that Lisa paid $0.42 for the first minute and $0.19(x - 1) for the remaining minutes.
We can set up an equation using the total cost of $2.89:
0.42 + 0.19(x - 1) = 2.89
To solve for x, we can simplify and solve the equation step by step:
0.19(x - 1) = 2.89 - 0.42
0.19(x - 1) = 2.47
Next, we isolate the term (x - 1):
x - 1 = 2.47 / 0.19
x - 1 = 13
Finally, we solve for x by adding 1 to both sides of the equation:
x = 13 + 1
x = 14
Therefore, the total length of the call was 14 minutes.
