Question

Marko currently has 20 tulips in his yard. Each year he plants 5 more. Write an explicit formula for the number of tulips Marko has.

Predict the number of tulips Marko will have in 7 years. If possible I’d like a step by step answer.

Answer 1

55

Explanation:

Marko has 20 now (after 0 years). In 1 year, he will have 5 more. That is, the number of additional tulips after x years is 5x. The formula for the number of tulips (y) after x years can be written ...

y = 20 +5x

In 7 years, x=7 and the number of tulips will be ...

y = 20 +5(7) = 20 +35 = 55

Marko is predicted to have 55 tulips in 7 years.
