I need help ASAP;
Algebra 1: I think it's about exponential growth.

Step-by-step explanation:

The given equation assumes a 12 cubic inch initial volume.  The question wants to know when, in minutes, the volume, y, reaches 36 in^3:

y = 12*(2)^(t/60), where t is time in minutes

Therefore:

36 = 12*(2)^(t/60)

3 = (2)^(t/60)

log(3) =(60/t) log(2)

t = 60log(3)/log(2)

t = 95.1 minutes

$0.71

Step-by-step explanation:

9.99 + (3% of 9.99) = 10.2897

11 - 10.2897 = 0.7103, so $0.7103 is our answer. However, this isn't a real amount of money that can be handed from a cash register to a customer. So, we will round it to the nearest cent, bringing us to $0.71, our final answer.
