A store reported total sales of $385

New price = 385

Old price (or Reference price) = 320

[(new prince - old price) / old price] * 100 = % increase

[(385 - 320) / 320] * 100 = % increase

[(65) / 320] * 100 = % increase

Since there is a huge difference between values in answer choices:

[ 60 / 300 aprox.] * 100 = % increase

1 / 5 * 100 = % increase = 20 % increase

0,2 * 100 = 20 % increase
