one week gas was 1.25 per gallon the next week gas was 1.50 per GALLON by what percentage did the price increase

Therefore, the price increased by 20%

Step-by-step explanation:

Initial price = 1.25

Final price = 1.50

so price increased = 1.50 - 1.25

so,

price increased% = (0.25/1.25) × 100%

= 0.2 × 100%

= 20%

choice b is correct
