Answer:

Caleb's percent of increase from the first test to the second test is:

50%

Explanation:

Caleb scored 60 on his first math test.

For the next test he earned a score of 90.

Percentage increase=
(score\ in\ second\ test-score\ in\ first\ test)/(score\ in\ first\ test)* 100

Percentage increase=
(90-60)/(60)* 100

Percentage increase=
(30)/(60)* 100

Percentage increase=
(1)/(2)* 100

Percentage increase=50%

Hence, Caleb's percent of increase from the first test to the second test is:

50%
