Answer:
The equation that represents Mr. Thompson's weight after m months
y = 260 - 4m
Mr. Thompson will reach his goal weight after 10 months
Step-by-step explanation:
Current weight = 260 pounds
Number of months = m
Mr. Thompson loses 4 pounds per month
Let the weight of Mr. Thompson after m months be y
The equation that represents Mr. Thompson's weight after m months:
y = 260 - 4m
The goal weight = 220 pounds
260 - 4m = 220
4m = 260 - 220
4m = 40
m = 40/4
m = 10
Mr. Thompson will reach his goal weight after 10 months
