Answer: Minimum for $150: 2 Hours
Step-by-step explanation: First, Tiffany charges $30 per additional child. If she babysits for 4 children, you do 30 x 4, which is equal to 120. That would be the cost for the children. Now, if she charges $15 PER HOUR, then you just add up $15 + $15, which is $30, and you add that $30 to the $120. Which is $150. There you have it. If this is wrong, correct me please!
Answer:
12.1
Step-by-step explanation:
y=a(1/2)^t/h
270=410(1/2)^t/20
Divide both sides by 410
0.6585365854 = (1/2)^t/20
Log Both sides
Log(0.6585365854) / Log(1/2)
.6026645024= t/20
20 x .6026645024 = t
12.05329005 to the nearest tenth is 12.1 = t
<span>The answer is 60. Let x be the number we are looking for. So x is 100% and we know that 15 is 25%. Make a proportion: x : 100% = 15 : 25%. Cross the products: x * 25% = 15 * 100%. x * 25% = 1500%. x = 1500% : 25%. x = 60. Thus, 60 is 100%, and 15 is 25% of 60. </span>
