C = 50(P-2)

C = 50(25-2)

C = 50(23)

C = 1150 naira

Therefore, the cost of sending an email of 25 pages is 1150 naira.

b. To find the number of pages in an email message that costs 800 naira, we can rearrange the formula:

C = 50(P-2)

800 = 50(P-2)

16 = P-2

P = 18

Therefore, the email message contains 18 pages.

a. Find the cost of sending an email of 25 pages:

Substitute P = 25 into the formula:

C = 50(25 - 2)

C = 50(23)

C = 1150 Naira

Therefore, the cost of sending an email of 25 pages is 1150 Naira.

b. If it costs 800 Naira to send an email message, we need to find how many pages it contains:

Set the cost (C) equal to 800 and solve for P:

800 = 50(P - 2)

Divide both sides by 50:

16 = P - 2

Add 2 to both sides:

P = 18

Therefore, the email message contains 18 pages.
