25(2) + 7(1) + 3x = 78....x represents the number of 3 point shots
50 + 7 + 3x = 78
57 + 3x = 78
3x = 78 - 57
3x = 21
x = 21/3
x = 7....so there were 7 three-point shots made

You can model that you expect a 1.25% raise each year that you work for a certain company. If you currently make $40,000, how ma

Answer:

94 years

Step-by-step explanation:

We can approach the solution using the compound interest equation

$A= P(1+r)^t$

Given data

P= $40,000

A= $120,000

r= 1.25%= 1.25/100= 0.0125

substituting and solving for t we have

$120000= 40000(1+0.0125)^t \\\120000= 40000(1.0125)^t$

dividing both sides by 40,000 we have

$(1.0125)^t=\frac{120000}{40000} \\\\(1.0125)^t=3\\\ t Log(1.0125)= log(3)\\\ t*0.005= 0.47$

dividing both sides by 0.005 we have

$t= 0.47/0.005\\t= 94$
