Original shirt cost: $55. Current shirt cost $40 find the percent decrease round to the nearest whole percent

Step-by-step explanation:

Original cost = $55

Current price = $40

Decrease in price = 40-55 = - $15

Percentage decrease = [ (New price - old price) / old price] * 100

Percentage decrease = (40-55) / 55] * 100

= - 0.272727 * 100

= - 27.27%

To a whole percentage = 27%

Therefore, the cost of the t-shirt decreased by 27%
