Given
For each diamond you collect, you earn 80 point
earn 100 bonus points by completing the level in less than 2 minutes.
earn more than 1220 points to continue on to the next level
Find the inequality that represents the numbers dd of diamonds you must collect in less than 2 minutes to advance to the next level.
To proof
As given in the question
For each diamond earn point = 80
bonus points by completing the level in less than 2 minutes = 100
earn more than 1220 points to continue on to the next level
Let us assume that the number of diamond = d
The inequality written in the form
we get
now solving the above equation
Thus the numbers of diamonds you must collect in less than 2 minutes to advance to the next level be 14.
Hence proved
