Hello!

The two angles pictured are corresponding angles, so they are congruent.
Therefore:
17x - 4 = 12 + 15x
Isolate for x by subtracting 15x from both sides:
2x - 4 = 12
Add 4 to both sides:
2x = 16
Divide both sides by 2:
x = 8.
Answer is 4/2 hope it helps you
50k is the same as 50,000
73% = 73/100 = 0.73
Multiply 50,000 with 0.73
50,000 x 0.73 = 36500
You spend $36500.
Subtract 36500 from the total
50,000 - 36,500 = $13,500
$13,500 is the amount of money you have left.
hope this helps
