Answer:
14%
Step-by-step explanation:
Last year's score = 350
This year's score = 399
What was the percent of increase in Kenia's score
Percentage increase= (new score - old score) / old score × 100
= (399-350) / 350 × 100
= 49 / 350 × 100
= 0.14 × 100
= 14%
The percent of increase in Kenia's score is 14%

z = $13.14
