Final answer:
The Monster Truck's height increased by 20% after getting new tires.
Explanation:
The Monster Truck's height increased by 20%. To calculate the percent increase, you can use the formula: Percentage increase = (New height - Old height) / Old height x 100%. In this case, the increase is 2 feet (12 feet - 10 feet), and the original height was 10 feet. So, (2 / 10) x 100% = 20%.
