Answer: 40
Step-by-step explanation:
Answer:
a is 60 ft^3 and b is 45
Step-by-step explanation:
b is 45 because 60/4 is 15, which would mean that 4/4 is 60, and since it says 3/4, you subtract 15 from 60 to get 45.
a is 60 because volume equals length times width times height, the three measurements shown
(edit)
and when multiplied you get 60 altogether.
y = a(1-r)^×

y = exponential decay
a = initial amount = 78000
r = decay rate = .03
x = number of time intervals = w
Error:
b = growth/ decay factor
b = 1+r for growth
b = 1-r for decay
x = w per the above information
Sarah did not account for either of these points when creating her equation.
Correct solution:
y = 78000 (1-.03)^w
Uhh I wish I could help but I cannot I'm so sorry
