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
Now,
<u>a. How much does she pay for 5 sheets of pictures?! </u>
Putting p = 5 in the function
She will pay $100 for 5 sheets of pictures
<u>b. How much does she pay for "x" sheets? </u>
Putting x in place of p
<u>c. How many sheets can she buy for $145? </u>
We know the cost now, we have to find p so,
Dividing both sides by 15
Hence,
She can buy 8 sheets for $145
