PLEASE Help me with correct math word problem solutions!!!
I am not very good at math word problems. I just need someone to answer these questions not to try to teach me because that is why I am going to school only the teaching part is not working. So here I am asking for help to get these problems right. Thanks to whoever decides to help me!

1. Estimate the life time cancer risk for a 60 kg person exposed to a particular carcinogen under the following circumstances. Exposure time is 5 days per week, 50 weeks per year, over a 25 year period of time. The person is assumed to breathe 20 m3/day. The carcinogen has a potency of 0.02 (mg/kg/day)-1 and its average concentrati nis 0.05 mg/m3.

2. Calculate 1) how much gasoline you consume per year, 2) how much you spend for the gas per year assuming that the gas price is $2.6 per gallon, and 3) how much you generate CO2 by driving you rcar per year assuming that burning 1 gallon of gasoline produce 20 lb of CO2. Discuss how you can reduce your CO2 footprint.Dmarieg (talk) 21:31, 14 March 2010 (UTC)

Q1. Consider a carcinogenic VOC with the dose-response curve shown in the figure below. If 70-kg people breath 20 m3/day of air contaminating 0.001 mg/m3 of this VOC through their entire 70 years life time, estimate the cancer risk. I hope you can do this without the chart. I cannot copy it over or draw it here. But whatever anyone can do to help me I would be grateful. Thanks again!Dmarieg (talk) 22:15, 14 March 2010 (UTC)
