Mrrafil [7]

Given:

Book club A charges $20 for membership and $2 per book rental.

Book club B charges $10 for membership and $3 per book rental.

To find:

The number of books for which the cost be the same at both book clubs.

Solution:

Let x be the number of books.

Book club A charges $20 for membership and $2 per book rental. So, the total cost is

C_1=20+2x             ...(i)

Book club B charges $10 for membership and $3 per book rental. So, the total cost is

C_2=10+3x            ...(ii)

Equating (i) and (ii), we get

10+3x=20+2x

3x-2x=20-10

x=10

The total cost is

C_1=20+2(10)

C_1=20+20

C_1=40

Therefore, the total cost at both book clubs are same for 10 rental books and that cost is $40.

The penny size of a nail indicates the length of the nail. The penny size d is given n 1by the literal equation d=4n−2, where n
Mars2501 [29]

Answer:

a) n=\frac{d+2}{4}

b)

When d = 3

n = (3+2)/4 = 5/4 inches

When d= 6

n = (6+2)/4 = 2 inches

When d = 10

n = (10+2)/4 = 3 inches

Step-by-step explanation:

<u>Complete Question:</u>

<em>The penny size of a nail indicates the length of the nail. The penny size d is given by the literal equation d=4n−2, where n is the length (in inches) of the nail.</em>

<em>a) Solve equation for n</em>

<em>b) Use part (a) to find length of nails with the following penny sizes: 3, 6, 10.</em>

<u>Solution:</u>

<u />

a)

We use algebra and take 2 to the other side and divide to solve for n. Shown below:

d=4n-2\\d+2=4n\\n=\frac{d+2}{4}

So,

n = (d+2)/4

b)

Since we have to find length of nails, we plug in 3, 6, and 10 respectively into d of the formula we found in part (a).

When d = 3

n = (3+2)/4 = 5/4 inches

When d= 6

n = (6+2)/4 = 2 inches

When d = 10

n = (10+2)/4 = 3 inches
