Answer:

Plug in each variable into the simple interest formula: I = PRT
P = $600
R = 8.5% (0.085)
T = 4 years
One company wants $10 per 3.5 hours, so they want 10 / 3.5 ≈ 2,86 dollars per hour (after rounding to the closest hundreths).
Second company wants $1.25 per half an hour, so they want 2 * 1,25 = 2,50 dollars per hour.
The unit rate is 2,86:2,50
A − 3b = 16
a = b − 2
b - 2 - 3b = 16
2b = - 18
b = - 9
a = - 9 - 2
a = - 11
(-11,-9)
