Answer:
6,000 dollars
Step-by-step explanation:
We first need to find out how much it would cost Danielle for a month if she chose the second option
200 + 40 = 240
240 x 30 = 7,200
Now that we know how much Danielle would pay if she chose the second option, now we need to find out how much she <em>saved</em>.
7,200 - 1,200 = 6,000
So Danielle saved 6,000 dollars by choosing the first option instead of the second one.
271, since if the last 4 numbers didn't change, you can only change the first 3, so that would be 270 different numbers, not forgetting just 2014 so it makes it 271
120/4 = 30 So the average cost of a lamp is $30
