Answer:
Step-by-step explanation:
Use the equation 2,000 = 16,000(1-r)^t to solve for t;
2000 = 16000(1-0.35)^t
Divide both sides by 16000
2000/16000 = 0.65^t
0.125 =0.65^t
Introduce logarithm on both sides;
<em>ln</em> 0.125 = t <em>ln</em> 0.65
Divide both sides by <em>ln</em> 0.65;
(<em>ln</em> 0.125) / (<em>ln</em> 0.65) = t
-2.07944/ -0.4308 = t
4.827 = t
t= 5 (as a whole number)
Therefore, the car is about 5 years old.
The number of hats sold = x
The number of t-shirts sold = y
Cost of selling of each hat = $5 and
Cost of selling of each t-shirt = $12.
Cost of x hats at the rate $5 each = 5x and
Cost of y t-shirts at the rate $12 each = 12y.
Total cost of x hats and y t-shirts = 5x+12y.
Total amount was spent = $240.
Therefore,<em> cost of x hats and y t-shirts should be greater than or equal to 240.</em>
<h3>So, the inequality for the situation would be </h3><h3>5x+12y ≥ 240.</h3>
