What I do is to add up the hundreds and tens in my mind first:
130 + 90 + 160 = 380
and then add the small change:
7.50 + 2.50 + 2.50 = 12.50
and add it back to the first amount
392.50

Answer:
x ≈ 83.533
y = 9105.13
Step-by-step explanation:
Step 1: Substitution
109x = 79x + 2506
30x = 2506
x = 83.533
Step 2: Plug <em>x</em> in
y = 109(83.533)
y = 9105.13
Graphically:
