Question

A kitten weighs 1.4 lbs at birth and gains 1.2 pounds per week. A puppy weighs 2.8 lbs and gains 0.5 pounds per week. In how many weeks will the kitten be more than the weight of the puppy?

a. 2 weeks
b. 3 weeks
c. 4 weeks

Answer 1

a. 2 weeks. The kitten will be more than the weight of the puppy after 2 weeks.

Step-by-step explanation:

To determine how many weeks it takes for the kitten to be more than the weight of the puppy, we need to set up an equation. Let's assume that after x weeks, the weight of the kitten will be more than the weight of the puppy. The weight of the kitten after x weeks is 1.4 + 1.2x pounds, and the weight of the puppy after x weeks is 2.8 + 0.5x pounds. Setting up the equation and solving for x:

1.4 + 1.2x > 2.8 + 0.5x
0.7x > 1.4
x > 2

Therefore, the kitten will be more than the weight of the puppy after 2 weeks.
