If the customer uses more than 450 minutes the payment is $39.99 for the first 450 minutes plus $0.45 for each minute over 450.
How do I convert this into an expression?
this is what I got, but my teacher says its not right,but its close and I am not sure how to convert that into an expression
getPayment = 450 * 39.99 + (minutes - 450) * 0.45
why are you multiplying $39.99 by 450 minutes.
The way I read it, you pay $39.99 for any part of the first 450 minutes.
so the equation should have been
getPayment = (minutes - 450)*0.45 + 39.99
I was multipling $39.99 by 450 because that's how much it is for 450 minutes.
getPayment = (minutes - 450)*0.45 + 39.99 still doesnt work.
Here are the rules for the equation
the first 450 minutes cost 39.99 per month
Additional minutes cost .45 per minute
Assuming that more than 450 minutes are used, it would be as follows:
$39.99 + $0.45(X - 450), where X is the total number of minutes used, just as Reiny indicated.
However, if X is not >450, don't expect to get a reduction in the basic rate of $39.99.
I hope this helps. Thanks for asking.

Math how to solve this math problem A cellular phone company offers a package called 'Statewide
500'. The charge is $39.99 per month, and it includes up to
500 min of statewide calling time. Minutes over 500 are charged at a rate of $0.40 per minute.
Determine the total charge for using a cell phone for
561 min in one month.
To convert the given information into an expression, we need to consider the different scenarios:
1. If the customer uses 450 minutes or less:
In this case, the payment is simply $39.99, as there are no extra minutes to consider.
2. If the customer uses more than 450 minutes:
In this case, the first 450 minutes will cost $39.99, and any additional minutes will cost $0.45 each.
So, the expression to calculate the payment would be:
getPayment = $39.99 + ($0.45 * (minutes - 450))
In this equation, "minutes" represents the total number of minutes the customer used.
Let's consider an example:
Suppose the customer used 600 minutes in a month.
Using the expression, we can calculate the payment as follows:
getPayment = $39.99 + ($0.45 * (600 - 450))
= $39.99 + ($0.45 * 150)
= $39.99 + $67.50
= $107.49
So, the payment for using 600 minutes would be $107.49.
Remember, it is important to always check the conditions and limitations given in the problem to ensure the expression accurately represents the situation.
