You're in high school and can't do this, wow that's sad since i'm in seventh grade. Anyway you divide 2 from $47.00 to get $23.50 and 3 divided by $47.00 to get $15.66 repeated. round to get $15.67 or $15.70.
1.6m=-4
Divide both sides by 1.6 to get m by itself
1.6m/1.6=-4/1.6
m=-4/1.6
m=-2.5
Answer: m=-2.5
