Subtract the cost from the revenue:
(-0.32x^2+270x) - (70x+52)
270x - 70x = 200x
The answer would be -0.32x^2 + 200x + - 52
This is what i did to get the answer.
225/ 4.5 = 50 seconds to finish the slushy.
Use Pythagoras theorem,
c² =a² +b²
x² =10² +10<span>²
</span>x<span>² =100+100
</span>x<span>² =200
</span>x=14.14
x=14.1
