Nikki makes $9.50 an hour working at Current Electronics. She plans to buy a DVD recorder that costs $269.60. Write and solve an inequality describing how many hours h Nikki will have to work to be able to buy the DVD recorder. 269.60 + h ≥ 9.50; 31 hours

9.50h ≥ 269.60; 29 hours

269.60 – h ≥ 9.50; 28 hours

269.60h ≥ 9.50; 30 hours

Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x
