Let the cost of a shirt be s.
Three shirts = 3s.
3s + 15 ≤ 80 (Answer F)
Answer:
Function 1 written in vertex form is f(x) = -x^2 + 8x - 15 = -(x^2 - 8x + 15) = -(x^2 - 8x + 16 + 15 - 16) = -(x - 4)^2 - (-1) = -(x - 4)^2 + 1
Therefore, vertex = (4, 1)
Function 2 written in vertex form is f(x) = -x^2 + 4x + 1 = -(x^2 - 4x - 1) = -(x^2 - 4x + 4 - 1 - 4) = -(x - 2)^2 - (-5) = -(x - 2)^2 + 5
Therefore vertex = (2, 5)
Function 1 has a maximum at y = 1 and function 2 has a maximum at y = 5. Therefore, function 2 has a larger maximum.

Answer:
It is a 40% increase
Step-by-step explanation:
So first of all the formula is
New-old/old
Or rate of change/ original
SO th new is 350
THe old is 210
350-210=140
140/350 which is old is 2/5
2/5 is 40 percent
So 40 percent increase
