Answer:
20 minutes on the stationary bike
10 minutes on the treadmill
Step-by-step explanation:
x = minutes on bike
y = minutes on treadmill
x + y = 30
12x + 15y = 390
x = 30-y
12(30-y) + 15y = 390
360 - 12y + 15y = 390
3y = 30
y = 10
x + 10 = 30
x = 20
use equation A(t) = a(1+r)^t to solve. you want to find the starting so solve for A
1000 = a(1+.03)^5
1000 = 1.1592740743a
a = $862.61
Point and Line because you use a line and points to make parallel lines, Parallel lines are made up of a line and points.
hope this helps have a nice nite!
