Question

Jordan's average monthly expenses are $450 less than half of her monthly income. The sum of her average monthly expenses and monthly income is $3600.

Answer 1

jordans monthly expenses = 900

jordan monthly income = 2700

Explanation:

jordan monthly expenses = x

jordan monthly income = y

x + y = 3600

x = 1/2y - 450

solve for x, 1/2y - 450 = x

+450 + 450

1/2y = x + 450

y = 2x + 900

2x + 900 + x = 3600

- 900 -900

3x = 2700, 3x/3 = 2700/3

x = 900

solve for y, 1/2y - 450 = 900

+ 450 + 450

1/2y = 1350, multiply 1/2y and 1350 by 2, y = 2700

y + x = 3600, 2700 + 900 = 3600
