Question

Last week we got 3.5 inches of snow. Six-tenths of an inch melted before another storm added 8.3 inches. Since then we have lost 4.2 inches to melting or evaporation. How many inches of snow are left on the ground?

Answer 1

3.5 - 0.6 = 2.9
2.9 + 8.3 = 11.2
11.2 - 4.2 = 7

Answer 2

3.5 - .6 = 2.9
2.9 + 8.3 = 11.2
11.2 - 4.2 = 7.0 inches left. :) :D
