In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
James total earnings:
last week = $900
Step 02:
equation:
we must analyze the problem to find the solution.
x = amount (last week)
total = $900
4 * x - 20 = 900
4x - 20 = 900
4x = 900 + 20
x = 920 / 4
x = 230
The answer is:
$230
