Travis, jessica and robin are collecting donations for the school band. travis wants to collect 20% more than jessica, and robin wants to collect 35% more than travis. if the students meet their goals and travis collects $43,how much money did they collect in all?
a $106.78
b $128.60
c $136.88
d $144.99

If you would like to know how much money did they collect in total, you can calculate this using the following steps:

Travis ... t = $43
Jessica ... j
Robin ... r

120% of j is t
120% * j = 43
120/100 * j = 43
j = 43 * 100 / 120
j = $35.83

r = 135% of t = 135% * 43 = 135/100 * 43 = $58.05

t + j + r = $43 + $35.83 + $58.05 = $136.88

The correct result would be C. $136.88.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
