It costs a baker 2x + 30 dollars to bake x muffins a day. Each muffin is sold for 5 dollars. How many muffins would the baker ne

Svetradugi [14.3K]

Answer:

X = 10

Step-by-step explanation:

The equation to use would be; 2x + 30 = 5x; because the baker is looking for enough to cover the costs, no more no less.

Then all you have to do is solve for the equation.

2x + 30 = 5x

Subtract 2x from each side

30 = 3x

Divide by 3

10 = x

The baker needs to sell 10 muffins in a day to make enough to cover the revenue.

The function has a maximum at (1, 3).

_____
You know it is not a minimum because the coefficient of the squared term is negative.

You know the vertex is (1, 3) because you match the pattern to

which has its vertex at (h, k).

Estimate the time Juanita will arrive at her aunt's home 320 miles away if she leaves at 9:00 a.m., drives about 60 miles per ho

uranmaximum [27]

Answer:

D. 3:00 p.m.

Step-by-step explanation:

d = Distance = 320 miles

s = Speed = $60\ \text{mph}=\dfrac{60}{3600}=\dfrac{1}{60}\ \text{miles/s}$

Time taken is given by

$t=\dfrac{d}{s}\\\Rightarrow t=\dfrac{320}{\dfrac{1}{60}}\\\Rightarrow t=19200\ \text{s}$

40 minutes break is $40\times 60=2400\ \text{s}$

Total time taken is $19200+2400=21600\ \text{s}=\dfrac{21600}{60\times 60}=6\ \text{hours}$ .

So, the entire trip took 6 hours. 6 hours after 9 a.m. is 3 p.m.
