Ibuy the same chips every week and my bill is normally $90.00. why am i now being charged $108 for the exact same items? what percentage has the store increased their prices?

20%

Step-by-step explanation:

My bill of the chips comes every week  = $90

Now the store is charging for the exact same items = $108

Increase in their prices = 108 - 90 = $18

The percentage of the increased amount = × 100

                                                                     = 0.2 × 100

                                                                     = 20%

The store has increased 20% in their prices.
