Answer:

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

50%

Step-by-step explanation:

Caleb scored 60 on his first math test.

For the next test he earned a score of 90.

Percentage increase=\(\dfrac{score\ in\ second\ test-score\ in\ first\ test}{score\ in\ first\ test}\times 100\)

Percentage increase=\(\dfrac{90-60}{60}\times 100\)

Percentage increase=\(\dfrac{30}{60}\times 100\)

Percentage increase=\(\dfrac{1}{2}\times 100\)

Percentage increase=50%

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

50%
