A tree seedling was 0.8 meter tall. It grew 5.5 meters per year for x years, and now it is 8.7 meters tall.

Answer 1

The equation \( 0.8x + 5.5 = 8.7 \) represents a situation where a value starts at 5.5 and increases by 0.8 for \( x \) weeks or time intervals, resulting in a current value of 8.7.

The correct response is:

A puppy weighed 5.5 pounds when it was born. It gained an average of 0.8 pound per week for \( x \) weeks, and it currently weighs 8.7 pounds.

This matches the equation, where \( 5.5 \) is the initial weight, \( 0.8 \) is the weight gain per week, and \( 8.7 \) is the current weight after those weeks.
