Question

a plant is 13 inches tall if it grows 2 inches every week how many weeks will it take for it to grow 23 inches

Answer 1

Answer:

We add the current height of the plant to the product of the rate it's growing per week (2 inches) and the number of weeks it grows (n) and set this equal to 23. Then we solve for n. Divide both sides by 2 and we get n = 5. In 5 weeks the plant will be 23 inches tall
