Answer:
estimate: $80
exact amount paid: $82
Step-by-step explanation:
If you round $246 to 240, then divide it by 3, you should get $80. The cost per pair should be around $80 each
For the exact answer you take the amount spent (246) and divide it by the amount of jeans she bought (3).
246/3 = 82
f(x)=lnx
y=f(x)
dy/dx= 1/x
tangent at (x,y) has slope 1/x
eqn of tangent is y = mx + c
since the tangent passes through origin, c=0
substitute y = lnx and m= 1/x to above eqn
lnx = 1
x=e
y=lne=1
<span>LMNO is a parallelogram
so NM = OL
x + 15 = 3x + 5
solve for x
x - 3x = 5 - 15
-2x = -10
x = 5
Answer
x = 5</span>
