Question

A plant is 8 cm tall, and grows 3 cm taller each week. How tall will the plant be after 25

weeks?

Answer 1

Answer:83

Explanation:

25 x 3 = 75

75 + 8 = 83

Answer 2

83 cm

Explanation:

let's make an equation for this situation. The plant starts at 8 cm and grows 3 cm every week. If x represents time in weeks and y represents height in cm, then:

y = 8+3x

filling in 25 for x, we find that:

y = 8+75

y = 83 cm
