Question

Express the total cost for printing 15 digital images at a service charging $0.80 per large print and $0.20 per small print in terms of 'n' prints in large format. Calculate the total cost if 5 of the 15 prints are in large format.

a. $8
b. $9
c. $10
d. $11

Answer 1

To calculate the total cost of printing 15 digital images, determine the number of large prints and small prints by subtracting the number of large prints from the total. The cost of large prints is $0.80 each, and the cost of small prints is $0.20 each. Add the cost of large prints and small prints to find the total cost.

Step-by-step explanation:

To calculate the total cost of printing 15 digital images, we need to determine the number of large prints and small prints. Let's assume 'n' is the number of large prints. Since there are 5 large prints and a total of 15 prints, the number of small prints will be 15 - 5 = 10.

The cost of each large print is $0.80, so the cost of 'n' large prints would be 0.80n. Similarly, the cost of each small print is $0.20, so the cost of 10 small prints would be 0.20 * 10 = $2.

To find the total cost, we add the cost of large prints and small prints: Total Cost = Cost of large prints + Cost of small prints = 0.80n + 2.
