Answer:
y = x - 7
Step-by-step explanation:
<span>Second angle = x
First angle = 2x
Third angle = x + 68
x + 2x + (x + 68) = 180
4x + 68 = 180
4x = 112
x = 28.
First angle = 56 degrees
Second angle = 28 degrees
Third angle = 96 degrees
Total = 180 degrees.</span>

Cost of the cat food- x
x= $17.9352 - $12.25
x = $5.6852
