Answer:
37.5%
Step-by-step explanation:
This week, the cost is higher when we compare to last week. Therefore, the percentage difference is given by comparing the price differences to the price for the previous week.
Difference in costs=165-120=45
Percentage difference with respect to last week's price= [tex]\frac {45}{120}\times 100=37.5%[/tex]
Therefore, percentage increase is 37.5%
