A baker determined the annual profit in dollars from selling cupcakes using p(n)=41n-0.06n2, where n is the number of cupcakes s
Andrej [43]

Answer:

The annual profit is $6384, if the baker sells 240cupcakes

Step-by-step explanation:

Annual profit in dollars from selling cupcakes = p(n)=41n-0.06n^2

where n is the number of cupcakes sold .

We need to find the annual profit if the baker sells 240cupcakes.

If baker sells 240 cupcakes, so we have n = 240

Putting value of n in the given equation and finding profit

p(n)=41n-0.06n^2\\Put\:n=240\\p(240)=41(240)-0.06(240)^2\\p(240)=9840-0.06(57600)\\p(240)=9840-3456\\p(240)=6384

So, The annual profit is $6384, if the baker sells 240cupcakes

Solve using linear combination. 8x+14y=4 -6x-7y+-10
emmasim [6.3K]

It's best to write the two equations as a vertical column:

8x+14y=4

-6x-7y = -10

Note that if we multiply the 2nd equation by 2, we get -12x - 14y = -20. The reason for wanting this version of the 2nd equation is that its -14y cancels the +14y in the first equation:

-12x - 14y = -20

8x+14y=4

Combine these equations, column by column. We get -4x = -16, which results in x = 4. Now find y by subbing 4 for x in either given equation. If we use the first equation, we get 8(4) + 14y = 4, or 32 + 14y = 4, or 14y = -28. Then y = -2.

The solution to this system of linear equations is thus (4,-2).

Check this result by substitution of these coordinates into -6(4) - 7y = -20:

-24 - 7(-2) = -10. Is this true or not?

-24 + 14 = -10 is true. Thus, (4,-2) is the desired solution.

2.5 kg cost £1.40<br><br>work out the cost of 4.25kg
Mkey [24]

Calculating the cost of 4.25 kilogram(kg) is £2.38, by multiplying it by 4.25 kg by 1 kg.

<h3>Cost</h3>

Costs are the expenses incurred in the manufacture, marketing, or preparation of a good or asset for regular use. In other terms, it's the cost incurred to produce a good, buy inventories, sell goods, or prepare equipment for use in a commercial activity.

Given,

2.5 kg cost  £1.40 i.e,

2.5 kg = £1.40

For 1 kg= \frac{1.40}{2.5}

= £0.56

To find the cost of 4.25 kg:

Then,

1 kg = £0.56

4.25 kg = 0.56 x 4.25

= £2.38

£2.38 is the cost of 4.25kg after calculating it.
