Answer:
Step-by-step explanation:
B. The system has infinitely many solutions. The system has one solution.
Here's the equation for one year:
0.0129(680) + 680
But because it is 3 years:
3(0.0129(680)) + 680
0.0387(680) + 680
We can make it simpler:
1.0387(680)
Multiply:
706.316
We can round up:
She will have $706.32, and earn $26.32
Answer:
(1)
x = 128/3
y = 52/3
(2)
x=3
Step-by-step explanation:
(1)
x+y=60 => 3y=52 => y=52/3 => x=128/3
x=2y+8
(2)
M1V1 + M2V2 = MV
x × 10 + x × 70 = 6 × 40
80x = 240
x = 3
