Best ResponseYou've already chosen the best response.0y = 150 (target number of deaths) 150 = 2.2 x (year1990) +216 Subtract 216 from each side 66 = 2.2 x (year 1990) divide both sides by 2.2 30 = year1990 Add 1990 to each side 2020 = year So in 2020 the cancer deaths will be 150 per year.

Best ResponseYou've already chosen the best response.0y = 2.2x + 216 > 2.2x = 216  y > x = (216  y) / 2.2 substituting y = 150 > x = 66 /2.2 = 30 so in year 2020 (1990 +30) cancer death rate will be 150.
