Question

The number of text messages Lelah sent each month is shown in the table. She can send no more than 55 messages each month without being charged. Use the inequality t < 55, where t is the number of text messages in a month, to determine in which months she exceeded her limit. If each additional text costs $0.25, how much was Lelah charged from January to April?

Answer 1

$0.75, because she only went over once in January, and twice in February. March was 55 and April was 51. So .25+.50=.75
