Answer:

Step-by-step explanation:

please find the complete question in the attached file.

In 1970, the hourly wage was determined using the formula:

$\to f(x) = 0.183(x - 1970) + 3.03$

So, the hourly wage in 1970:

$=f(1970)\\\\ = 0.183(1970 -1970) + 3.03\\\\ =0.183(0) + 3.03\\\\= 0+3.03\\\\=3.03$

ziro4ka [17]

Answer:

8.43 years

Step-by-step explanation:

Given data

Cost price P= $4995

Rate r= 10%

FInal amount A= $2150

The expression for the time/duration is given as

t= ln(A/p)/r

t= ln(2150/4995)/0.1

t= ln(0.430)/0.1

t= 0.843/0.1

t= 8.43

Hence the time it will take is 8.43 years
