Step-by-step explanation:

1) P = 47,100 + 2,550t

Given P = 95000

So,

95000 = 47100 + 2550t

Subtract 47100 from both sides,

95000 - 47100 = 2550t

47900 = 2550t

Divide by 2550,

t = 47900/2550 = 18.78 = 18.8 years

2) Given P = 43,100 + 3,150t

Both P must be equal.

47100+2550t = 43100+3150t

Subtract 43100 and 2550t from sides,

47100- 43100 = 3150t - 2550t

4000 = 600t

Divide by 600,

t = 4000/600 = 6.67 = 6.7 years
