x = 1240-y can be used to model the situation where x is the amount earned in second week.
Step-by-step explanation:
Given,
Total amount earned = D = $1240
Amount earned in first week = y = $480
Let,
x be the amount earned in second week.
Therefore,
Total amount earned = Amount earned in 1st week + 2nd week amount
D = x + y
1240 = x + y
Solving for x;
[tex]x= 1240- y [/tex]
x = 1240-y can be used to model the situation where x is the amount earned in second week.
