Question

The cost to print Alice’s 4 by 5-inch photo is $0.45. Assuming that the cost per square inch of photo is constant, how much should it cost to print the enlarged photo? Explain how you found your answer.

Answer 1

0.0225 for every inch increased in size for the printing the the photo

Explanation:

*I'll start off by using this section to show my work...*

4 x 5 = 20
`in^(2)` meaning that for every number multiplied with another, the total area of inches will be "Χ".

20 inches = [$]0.45

Meaning, for every 20 inches, 0.45 will duplicate... For example, 40 (Which is 20 + 20..) will be .45 + .45 = 0.9 (0.90), but half of 0.45 will be 0.225 making the area of inches 10.

0.45/20 = 0.0225 per inch squared.

Therefore, the answer for the cost to print the enlarged photo will be 0.0225 per inch upped.
