Answer:
t = 21d
Step-by-step explanation:
Here tension and distance are denoted t by d and respectively. Since t varies directly with d , then the relation between t and d is k=td Given that, for the tension 42 pounds, the spring is stretched 2 inches. Substituting t = 42 and d= 2 into t = kd find the value of k . Therefore,
42= K (2)

K= 21
Thus the relationship is t = 21d

In this question, we need to find this year's tuition.
We know that last year's tuition was 29,613 dollars.
We know that this year's tuition increased by 5.9%
In order to find your answer, we would have to multiply 29,613 by (1 + 0.059 = 1.059), since the price is increasing.
Solve:
29,613 · (1 + 0.059 = 1.059)
29,613 · 1.059 = 31,360.167
If you have to round to the nearest hundredths, it would be: 31,360.17
If you have to round to the nearest whole, it would be: 31,360
This means that this year's tuition was $31,360
Answer:
$31,360 (if you need to round to the nearest whole)
$31,360.17 (if you need to round to the nearest hundredths)
