Lisa’s new cellular phone plan costs $39.99 per month plus $.15 per minute and $.24 per text message. as part of the plan, she gets 250 free minutes and 10 free text messages. if she talked for a total of 5 1/2 hours and sent 32 text messages in her last billing cycle, what were her total charges before tax?

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
