Answer: Choice B
48 + n = 56.5
============================================================
Work Shown:
48 = height last year, in inches
n = number of inches she grew last year
48+n = current height right now, in inches
48+n = 56.5 since her current height is 56.5 inches
Side notes:
- 48 inches = 4 feet
- 56.5 inches = 4.71 feet (approximate) = 4 ft, 8.5 inches (exact)
- To convert from inches to feet, you divide by 12.
- The equation in bold solves to n = 8.5, meaning she grew 8.5 inches over the last year.
