Answer:
The variable expression equation of the situation is;
x + 5 + x + 3·x - 7 = $73
The amount of money Jadah collects = $15
The amount of money Martez collects = $20
The amount of money Roana collects = $38
Step-by-step explanation:
The given parameters are;
The total amount of money they collect together = $73
The amount of money Martez collects = 5 + The amount of money Jadah collects
The amount of money Roana collects = 3 × The amount of money Jadah collects - 7
Let x represent the amount of money Jadah collects
Therefore, we have;
The amount of money Martez collects = 5 + x
The amount of money Roana collects = 3 × x - 7
The variable expression equation of the situation is given as follows;
The total amount of money the three collected = x + 5 + x + 3 × x - 7 = $73
∴ 5 × x - 2 = $73
5 × x - 2 = 73
5 × x = 73 + 2 = 75
x = 75/5 = 15
x = 15
The amount of money Jadah collects = x = $15
The amount of money Martez collects = 5 + x = 5 + 15 = 20
The amount of money Martez collects = $20
The amount of money Roana collects = 3 × x - 7 = 3 × 15 - 7 = 38
The amount of money Roana collects = $38
