Question

Write an expression That represents the weight of an object that weighs 12 pounds and increases by 0.5 pounds per month.

Answer 1

y = (0.5 pounds/month)x + 12 pounds

Explanation:

Let y be the weight of the object and x the time in months.

y = 12 (pounds) at month 0

y = (0.5 pounds/month)*x is the amount added for each additional month afterwards.

y = (0.5 pounds/month)x + 12 pounds
