38. Emily is buying some graduation pictures. She pays $25 for the sitting and $15 for each

goldfiish [28.3K]

a. She pays $100 for 5 sheets

b. 25+15x dollars for x sheets

c. 8 sheets

Step-by-step explanation:

Given

Sitting cost = $25

Per sheet picture cost = $15

Let p be the number of sheets of pictures

Then the cost can be written as a function of p

$c(p) = 25+15p$

Now,

a. How much does she pay for 5 sheets of pictures?!

Putting p = 5 in the function

$c(5) = 25 + 15(5)\\= 25+75\\=100$

She will pay $100 for 5 sheets of pictures

b. How much does she pay for "x" sheets?

Putting x in place of p

$c(x) = 25+15x$

c. How many sheets can she buy for $145?

We know the cost now, we have to find p so,

$145 = 25+15p\\145-25 = 25+15p-25\\120 = 15p$

Dividing both sides by 15

$\frac{15p}{15} = \frac{120}{15}\\p = 8$

Hence,

She can buy 8 sheets for $145
