2. a regional honor society selected high school students from four cities. 15% of the students came from rocklin. of the students came from loomis.- of the students came from roseville. there were 63 students from auburn. how many students were there in all? 5 4= 0.6 0.61 +d 63-x +1.5 4-1.5 6oshelatr

Part a:

given  where  represents the initial value of the fuel at 0 months. the value  represents the multiplier and the variable  represents the number of months.

the multiplier indicates whether an exponential function growing or decaying. multiplier > 1 indicates growth whereas multiplier < 1 indicates decay.

multiplier 1.04 in this context represents a 0.04 increase which as percentage is 4%

hence,  is an increasing function with 4% compound increase monthtly

part b

as  increases in ones,  increase by the ratio of  (rounded to 2 dp).

the value 1.06 represents increase by 0.06 which as percentage is 6%

hence, the fuel b has a greater percentage monthly increase
