11' x 15' = total area of 165 square feet. If the price per square foot is $19.95, then multiply the total square feet by the price per square foot to arrive at the total cost. 165 x $19.95 = $3291.75
Add the extras --- +853.99
Total ----- = $4145.74
Since it starts at 50 and goes to 35....it is a decrease since the amount is going down, or getting smaller. To find the percent, first find the difference 50-35 = 15; then divide by the initial amount of 50. So, 15/50 = 0.3, and then convert that to a percent by multiplying by 100. Therefore the percent decrease is 30%
