In May, Susana earned $40 from pet-sitting. In June, her earnings increase 200%. How much does she earn in June? Use the math you already know to help understand the problem. a. First consider 100%. What is 100% of $40? b. How does 200% compare to 100%?​

What mathematical statement is missing ? ? the answer is b

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
