Answer:
$16.30
Step-by-step explanation:
So if you can buy 3 lollipops for $4.89, then you can by 1 for $1.63. Then 10 lollipops would be $16.30.
Answer: No solutions
Step-by-step explanation:
|x|+5<1
Subtract 5 from both sides.
|x| < -4
No solutions is possible
Using the exponential function, it is found that the oxygen level at 10 miles is of 59.87 ppm.
<h3>What is the exponential function for the oxygen levels?</h3>
The oxygen levels in ppm for an altitude of x miles at the Mount Everest is given by the following exponential function:

In this problem, the altitude is of x = 10 miles, hence the oxygen level in ppm is of:

Answer:
x -2y = -9
Step-by-step explanation:
We can start by swapping the coefficients of x and y, then negating one of them. We can finish by evaluating the expression at the given point to find the constant.
2x -4y = constant
2(1) -4(5) = -18 = constant
So, an equation could be ...
2x -4y = -18
We notice that all of the coefficients of this equation are divisible by 2, so we can remove a factor of 2 from the equation:
x -2y = -9

Answer:
a) profit has a typical curve: negative at low volume, and again at very high volume.
b) $239,407
Step-by-step explanation:
a) The graph is negative below x=1.58, so the break-even point is 158 toys sold. The profit declines steeply above 533 toys sold, to again go negative for 774 toys sold. This sort of curve seems fairly typical.
__
b) The profit is a maximum of $239,407 when 533 toys are sold.
