Answer:
What is w equal to?
Step-by-step explanation:
from 2007 to 2012 is only 5 years, so we can see this as a compound interest with a rate of 1.2% per annum for 5 years, so

210 because 7th graders washed 12 cars, 8th graders washed 14 cars, 6th graders washed 16 cars. Added all together and multiplied by 5, it equals 210
X-5+5x-12=25
x+5x=25+5+12
6x=42
x=42/6
x=7
Answer:
Step-by-step explanation:
Step one- Find out how much it costs for one Lizard In this case, for four lizards it costs $47.88. To find the price for one lizard you divide 47.88 by four
$47.88/4Lizards=$11.97 per lizard.
Step two- Now that we have the price for one lizard, your question asks you how much for 6 lizards. We need to find that cost. To do so you multiply $11.97 by 6 for the lizards.
Your answer is $71.82
