raquel measures the height of a plant as it grows. it is 3 cm tall when she first measures it, and it grows 0.5 cm per day. let h represent the height of the plant, and let d represent the number of days since raquel started measuring the height. write an equation relating h to d.

d equals 0.5 plus 3 h

d equals 3 plus 0.5 h

h equals 0.5 plus 3 d

h equals 3 plus 0.5 d
