Solve the problem.Each bank teller at Bank4U is first given a 7% cost-of-living raise and then a $1650 merit raise. Write a function that transforms each old salary x into a new salary N(x). Does it make any difference in which order these raises are given? Explain.
A. N(x) = 1.07x + 1650; Yes, because 7% of the current salary, x, is less than 7% of the sum of $1650 and the current salary, (1650 + x). B. N(x) = 1.07(1650 + x); No, they would be the same amounts either way. C. N(x) = 0.07(1650 + x); Yes, because 7% of the current salary, x, is less than 7% of the sum of $1650 and the current salary, (1650 + x). D. N(x) = 0.07x + 1650; Yes, because 7% of the current salary, x, is less than 7% of the sum of $1650 and the current salary, (1650 + x).
