Question

In 15 minutes Frankita created 15 drawings. In 30 minutes she created 17 drawings. In 45 minutes she created 20 drawings. In 60 minutes she created 24 drawings. If Frankita continues making drawings in the same pattern, how many total drawings will Frankita have created at the end of 75 minutes?

Answer 1

The correct answer is D) 35

Explanation:

You can start from 60 minutes = 24 and continue the to add +1 so we start at + 5

24 + 5 = 29 75 min

29 + 6 = 35 90 min

Hence the answer is D) 35

Answer 2

Frankita will create 29 drawings at the end of 75 minutes.

Explanation:

Now below shown is the pattern used by Frankita:

15 min = 15 drawing

30 min = 17 drawing ⇒ increase by 2 (15+2 = 17)

45 min = 20 drawing ⇒ increase by 3 (17+3 = 20)

60 min = 24 drawing ⇒ increase by 4 (20+4 = 24)

75 min = 29 drawing ⇒ increase by 5 (24+5 = 29)

Hence We can say that Frankita will create 29 drawings at the end of 75 minutes.
