 Question 27351: The cost of a computer decreases from \$1500 to \$1200 after 3 months. Find the percent decrease? Could someone please help????Answer by Z(8)   (Show Source): You can put this solution on YOUR website!First calculate how much the cost actually decreased. \$1500-\$1200=\$300 Now you want to figure out \$300 is what percent of \$1500 (your original cost) so you divide \$300 by \$1500 and get 0.2 Multiply 0.2 by 100 to turn it into a percent, and you find out that your computer's cost decreased 20%.
