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%
I think its 20 but I'm not sure
Answer:
32
Step-by-step explanation:
f(x)= 3(x-2)² + 5
Let x = -1
f(-1)= 3(-1-2)² + 5
Parentheses first
f(-1) = 3(-3)^2 +5
Exponents
f(-1)= 3*9 + 5
Multiply
f(-1) = 27+5
Add
f(-1) = 32
X = 1 ± √13
