Multi Alternative Decision Structures Read the scenario listed below and using the blocks construct the algorithm to solve the problem. Not all blocks will be used. Use indenting to differentiate the condition from the action. You will have multiple attempts to solve the problem. Construct an algorithm that will determine how much the increase rate is given the amount of water usage. When water usage is above 100 gallons the increase rate is 25%. When the water usage is above 75 gallons the increase rate is 20%. When the water usage rate is above 50 gallons the increase rate is 15%. When the water usage is above 25 gallons the increase rate is 10%. Water usage that is 25 gallons or less is subject to no increases. Drag from here increase=0.15 increase=0.10 increase=25% increase=20% else if water_usage >50 then else if water_usage >75 then increase=15% increase=10% else if water_usage >25 then if water_usage >100 then else increase =0.0 end if
