3. Haley, Chuck, Dana, and Chris enter a contest to see who could bake the most chocolate chip cookies in an hour. Haley bakes 5

otez555 [7]

Chris baked 95 cookies.

Step-by-step explanation:

Given,

Cookies baked by Haley = 50

Cookies baked by Chuck = 65

Cookies baked by Dana = 90

Average of them = 75

Let,

Cookies baked by Chris = x

Average = $\frac{Sum\ of\ quantites}{No.\ of\ people}$

$75=\frac{50+65+90+x}{4}$

Multiplying both sides by 4

$4*75=\frac{50+65+90+x}{4}*4\\300=205+x\\300-205=x\\95=x\\x=95$

Chris baked 95 cookies.

Solve for n 50 points <br><br> a=p(1+r/n)^rn

Andreyy89

Answer:

$n = \frac{r}{\sqrt[nt]{\frac{a}{p}} -1 }$

Step-by-step explanation:

$a=p(1+\frac{r}{n} )^{nt}$

$\frac{a}{p} =(1+\frac{r}{n} )^{nt}$

$\sqrt[nt]{\frac{a}{p}} =(1+\frac{r}{n} )$

$\sqrt[nt]{\frac{a}{p}} -1 =(\frac{r}{n} )$

$n = \frac{r}{\sqrt[nt]{\frac{a}{p}} -1 }$

[ Do not confuse, as there are 2 n's, one in subject and another as power. We can never make the power or in a root, the subject. In order to solve for n, we have to make the character "n", the subject. ]
