Step-by-step explanation:
Part (a):
Since new payment amount is 20% less than the original, we can write
New Earning = N = $18 - (20%) ($18)
N = (80%)($18)
N = 0.8 * 18
N = $14.4
Part (b):
New number of errors are one-third () of the initial 15 errors,
Therefore, new number of errors = E =
E =
E = 5
It is given that, earnings per error = n = 15 cents = $0.15
Thus, we can calculate the total earnings for new number of errors as follows,
New Total Earning = N = n * E
N = 0.15 * 5
N = $0.75
