Answer 1

b. 393%

Explanation:

1.37 + 1.37x% = 4.02

Answer 2

Answer: Answer is 193% or c

Step-by-step explanation: To solve this, we can use algebra. Suppose x represents the percent of increase. 1.37 * x = 4.02. Divide both sides by 1.37 to get x = 2.93. This represents 293% However, since it is asking for the increasing, we need to subtract 100% since we only want to increase, not the total value.
