After n years,
244+20n = 300+12n
8n = 56
n=7
So, in 7 years they will both be 384 cm tall
A young Colorado spruce tree is growing at a rate of 20 cm per year. Currently, it is 244 cm tall. A 300 cm tall white spruce tree is growing at a rate of 12 m per year. In how many years will the two trees be the same height? Solve algebraically
