Answer:

The correct answer is option C. y = 31x + 154.

Step-by-step explanation:

Since x represents the days and she learns 31 words per day you would need to multiply 31 and the number of days (x).

This would look like 31x.

We also know she already knew 154 from the beginning which means we just have to add 154.

This leaves us with the equation y=31x + 154.

Hope this helps!

Cullumber company had $170,000 of net income in 2021 when the selling price per unit was $152, the variable costs per unit were
taurus [48]

The number of units sold in 2021 = <u>13,300 units</u>.

The number of units that would have to be sold in 2022 to reach the stockholder's desired profit level = <u>15,200 units</u>.

Assuming that Cullumber company sells the same number of units in 2022 as it did in 2021, the selling price in order to reach the stockholder's desired profit level = <u>$160</u>.

The net income of a company is its profit function, derived by the formula:

Profit = Sales - Cost.

Sales are the product of the number of units sold and per unit selling price.

Cost is the sum of fixed costs and the product of the number of units produced to the variable cost per unit.

Assuming the number of units sold in 2021 to be x,

we can say sales = $152x, and

cost = ${574800 + 96x}.

Therefore, profit = sales - cost,

or, 170000 = 152x - {574800 + 96x},

or, 170000 = 56x - 574800

or, 56x = 574800 + 170000 = 744800,

or, x = 744800/56 = 13300.

Therefore, the number of units sold in 2021 was <u>13,300</u>.

In 2022, the desired profit = $170,000 + $106,400 = $276,400.

Assuming the number of units sold in 2022 to be n, at the same unit data and fixed cost, we can say that:

Sales = $152n, and

Cost = ${574800 + 96n}.

Therefore, profit  sales - cost,

or, 276400 = 152n - {574800 + 96n},

or, 276400 = 56n - 574800,

or, 56n = 574800 + 276400 = 851200,

or, n = 851200/56 = 15200.

Therefore, the number of units sold in 2022 should be <u>15,200</u> to reach the desired profit of the stakeholders.

When the number of units sold in 2022 is the same as in 2021, that is, the number of units = 13,300, we assume the per unit selling price to be $P.

Now we can say that,

Sales = $13300P.

Costs = ${574800 + 96*13300} = ${574800 + 1276800} = $1851600.

Therefore, profit = sales - cost,

or, 276400 = 13300P - 1851600,

or, 13300P = 1851600 + 276400 = 2128000,

or, P = 2128000/13300 = 160.

Therefore, the new selling price per unit to reach stockholders' desired profit, assuming the number of units sold in 2022 to be the same as in 2021 is <u>$160</u>.

In pea plants, flower color is inherited in a Mendelian fashion. Purple flowers (P) are dominant over white flowers (p). If two
RideAnS [48]

Answer:

25%

Step-by-step explanation:

The crossing between two heterozygous purple flowers can have the following results:

P from 1st flower and P from 2nd flower: PP -> 25% chance

P from 1st flower and p from 2nd flower: Pp -> 25% chance

p from 1st flower and P from 2nd flower: Pp -> 25% chance

p from 1st flower and p from 2nd flower: pp -> 25% chance

As the purple flower gene is dominant over the white flower, to have a white flower we need to have only white flower's genes, that is, pp.

So, the probability of the offspring will have white flowers is 25%
