Question

The chubby bunny weighs 5 pounds, and it gains 3 pounds per year. The fat cat weighs 19 pounds, and it gains 1 pound per year. When will the two animals weigh the same amount?

Answer 1

Answer: 7 years

Step-by-step explanation:

The Chubby bunny currently weighs 5 pounds but is increasing by 3 pounds per year. Assuming we wanted to find the weight in a given year, we can assume that given year is x. The expression would be:

= 5 + 3x

The fat cat weighs 19 pounds and gains by 1 pound a year.

Expression is:

= 19 + 1x

Equate the two equations together and find x:

5 + 3x = 19 + 1x

3x - 1x = 19 - 5

2x = 14

x = 14/2

x = 7 years
