Answer: 10.7 years.
Step-by-step explanation:
7,300 * (1 + 0.015)^x = 8,560 <=>
7,300 * 1.015^x = 8,560 <=>
1.015^x = 8,560 / 7,300 <=>
1.015^x = 1.1726 <=>
x = 10.694
To the nearest tenth:
x = 10.7 years
74 = 20(2.5) + 20(x)
74 = 50 + 20x
74-50 = 20x
24 = 20x
24/20 = x
1.2 = x
x = 1.2 yards of red felt
