2149 x 25/100 = 537.25
1st year - 214 - 527.25 = 1611.75
2nd year - 1611.75 x 25/100 = 1208.81
3rd year - 1208.81 x 25/100 = 906.60
Ans : 906.60
Answer:
n = -9
Step-by-step explanation:
4(0.5n − 3) = n − <u>0.25(12 − 8n)</u>
2n - 12 = n - <u>3 + 2n</u>
2n - 12 = 3n - 3
2n - 3n = - 3 +12
-1n = 9
n = -9
Answer: 3 1/3 hours
Step-by-step explanation:
Tina rate: 1/5 job/hr
Together rate: 1/2 job/hr
Tyra rate: 1/x job/hr
---------
Equation:
rate + rate = together rate
1/5 + 1/x = 1/2
2x + 10 = 5x
3x = 10
x = 3 1/3 hrs (time for Tyra to do the job alone)
