Answer:
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%

Answer:
l(l - 2) = 168
Step-by-step explanation:
Let w = width
Let l = length
Let A = area
w = l - 2
A = l * w
also, A = 168
equating the two values of A
l * w = 168
l * (l - 2) = 168
l^2 - 2l = 168
l(l - 2) = 168
