media services charges $20 for a phone and $30/month for its economy plan. what is the total cost for 10 months service
C(t)= 30t +20=
total cost is $500 for 10 months?
You're paying way too much if the total cost is $500 for ten months. You only pay once for the phone.
C = (30 * 10) + 20
C = ?
C=300+20
C= $320 total cost
or did i miss the boat again?
You have it right this time! :-)
320! i thinkk
To calculate the total cost for 10 months of service, we need to multiply the monthly cost by the number of months and add any one-time charges.
In this case, the monthly cost is $30 and the one-time charge is $20 for the phone. Since we're considering 10 months of service, we multiply the monthly cost by 10:
10 months * $30/month = $300
Now, we add the one-time charge of $20:
$300 + $20 = $320
Therefore, the total cost for 10 months of service is $320, not $500.
