Answer:
The correct option is;
Marissa can talk for at most 192 minutes
Step-by-step explanation:
The amount for which Marissa buys the prepaid cell phone card = $25
The charge for a phone call using the recharge card = $0.13 per minute
The greatest number of minutes Marissa can call is given by the the following inequality;
t < $25/($0.13/minute)
$25/($0.13/minute) = (192 + 4/13) minutes
Therefore;
t < (192 + 4/13) minutes
The cost of 192 minutes = 192 minutes × $0.13 per minute = $24.96
The amount of credit left on the $25 recharge = $25 - $24.96 = $0.04
The minimum charge for calls = $0.13
The amount remaining after 192 minutes $0.04 is less than the amount to make a call $0.13
Therefore;
t ≤ 192 minutes
Therefore, Marissa can talk for at most 192 minutes.

Answer:
18x + 28 is the perimeter
Step-by-step explanation:
As perimeter is the som of all side
So P = 6x+8 + 3x+6 + 6x+5 + 2x+2 + 3 + x+4
= 6x+3x+6x+2x+x + 8+6+5+2+3+4
= 18x + 28
Here is the solution to the given problem above.
Given that for an 8 pound bag of tomatoes costs $5.60, we would want to know how much will it be for 11 pounds. First, we should know how much does it cost per pound. So 5.60 divided by 8 is 0.7. So per pound of tomatoes costs $0.7. Now to know how much for 11 pounds, we multiply 0.7 by 11 and we get $7.70. The correct answer therefore would be option C. $7.70. Hope this answer helps.
