Final answer:
To calculate a 30% increase of 62 kVp, you multiply 62 by 0.30 to get 18.6 kVp, and then add that to the original 62 kVp for a total of 80.6 kVp, which is approximately 81 kVp.
Step-by-step explanation:
When 62 kVp is increased by 30%, we can calculate the new kVp value with a simple percentage increase calculation. To find the 30% increase of 62 kVp, first calculate 30% of 62 kVp, which is 0.30 × 62 kVp = 18.6 kVp. Then, add this increase to the original 62 kVp, giving us 62 kVp + 18.6 kVp = 80.6 kVp.
Rounding to the nearest whole number, we get approximately 81 kVp, which is closest to answer choice a) 80 kVp.
