Answer:

  55

Step-by-step 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.
