Answer: 187.68 pounds
Explanation:
Since Mr Roxbury lost 32% of his body weight, his body weight will be:
= 240 - (32% × 240)
= 240 - (0.32 × 240)
= 240 - 76.8
= 163.20 pounds
Since he later gained 15% back, we'll then add the value of 15% to his post diet body. This will be:
= 163.20 + (15% × 163.20)
= 163.20 + (0.15 × 163.20)
= 163.20 + 24.48
= 187.68 pounds
After the two years, he weighed 187.68 pounds.
