QUESTION 1 : The pay for a mathematics major graduating from college is given by the formula P= 47, 100 + 2,550t where T represents years worked after college how many years would a mathematics major expect to work to be earning at least $95,000 per year? ROUND TO 1 DECIMAL PLEASE.

__________ years

QUESTION 2: The pay for a government major graduating from college is given the formula P = 43, 100 + 3, 150t. If a mathematics major and a government major graduate and start working at the same time how many years will it take for the government major to earn at least the same amount as a mathematics major? ROUND TO 1 DECIMAL PLEASE.

At least_________ years

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
