Answer:

<h2>This constant of proportionality represents the lost fee, which is the relation between both variables.</h2>

Step-by-step explanation:

Givens

  • The lost fee is 75% of the cost of the book.
  • Sarah owes $60 to the school for the lost book.

Let's call c the cost of the book and f the lost feet. All this can be expressed as

f=0.75c

This expression indicates that the lost fee is 75% of the cost of the book.

Notice that this is a linear equation, where f and c are directly proportional and the constant of proportionality is 0.75, which is 75%.

This constant of proportionality represents the lost fee, which is the relation between both variables.

Now, replacing values we can find the cost of the book

60=0.75c\\c=\frac{60}{0.75}\\ c=80

The book costs $80.

Answer: 0.75,

The constant of proportionality is the ratio between two directly proportional quantities.

The cost of book changes but the lost book fee charge remains constantper book i.e.0.75


Step-by-step explanation:

Given: Let x be the cost of her book (in dollars).

Since, her school charges a lost book fee equal to 75% of the cost of the book.

Then, the the lost book fee=75% of x

Since 75% =0.75

Thus, the the lost book fee=$0.75x

The cost of book changes but the lost book fee charge remains constant per book i.e.0.75

Sarah received a notice stating that she owed the school $60 for he lost book.

The the lost book fee=0.75(60)=$45

Last year the population of Spoon Forks grew from 1250 to 1300. If the population of the town grows by the same percent this yea
Reptile [31]

Answer:

1352

Step-by-step explanation:

Firstly, we get the percentage growth last year. This is calculated as:

(1300-1250)/1250 * 100

= 4%

Now, we are assuming the growth rate is constant. So let’s calculate a 4% growth rate for this year. That would be:

4/100 * 1,300 = 52

The population this year would thus be 1300 + 52 = 1352

Pam and Amanda and Mike work at different clothing stores. Amanda made twice what Pam earned and Julie
Dmitriy789 [7]

Answer:

Pam: $181

Amanda: $362

Julie: $452

Step-by-step explanation:

(What does Mike have to do with this problem?)

Let a = Amanda's pay

Let p = Pam's pay

Let j = Julie's pay

"Amanda made twice what Pam earned"

a = 2p

"Julie made $90 more than Amanda"

j = a + 90

j = 2p + 90

Pam earned p

Total salary

a + p + j = 2p + p + 2p + 90

Total salary

$995

2p + p + 2p + 90 = 995

5p = 905

p = 181

a = 2p = 2(181) = 362

j = 2p + 90 = 362 + 90 = 452

Answer:

Pam: $181

Amanda: $362

Julie: $452
