It costs $3.95 to print a 12 in. by 16 in. color page. A friend needs to print a poster that is twice as long and twice as wide. At this rate, how much would he expect

to pay for the poster?

Price is determined by total area. The area of the original page is 192. If you calculate the area of the expanded posted, it would be 24*32. Which is 768. Find the scale factor of the areas, 768/192 is 4. 4*3.95 = 15.8. The price would be 15.80$.
