Answer:
[tex]\frac{80}{370}[/tex] OR [tex]\frac{8}{37}[/tex]
Step-by-step explanation:
So first you find the difference between the new cost and the old cost:
450 - 370 = 80
So the increase was 80.
When you write it as a fraction you write the increase ( 80 ) over the starting cost ( 370 ).
Thus the answer becomes [tex]\frac{80}{370}[/tex]
But you can always reduce it to its lowest terms thus:
[tex]\frac{8}{37}[/tex]
