<p>I think the answer is 11+0.62x.
The way I interpreted this was that if the total kWh of the month is less than or equal to 1500, you gotta pay $0.67 per kWh, but if the total kWh of the month is greater than 1500, you gotta pay $0.62 for each kWh. Therefore, I think adding 0.67x is irrelevant.</p>
<p>They stated that x>1500 so it would be 11+0.067(1500)+0.062(x-1500)</p>
<p>I interpreted it as the first 1500 cost .67 each and every one on top of that cost .62.</p>
<p>They stated that x>1500 so it would be 11+0.067(1500)+0.062(x-1500)</p>
<p>You would be correct sir.</p>
<p>O.O, i got it wrong… tricky question? - -|| O.O</p>
<p>what choice was that, if any of you remember
i think it was the last, right?</p>
<p>last choice theman
that is correct I do believe =)</p>
<p>wasnt it 2nd to last? i know the one about the correct answer choice was just like 11+.62(1500)</p>
<p>uhmm i think this problem is too ambiguous.</p>
<p>they say that x < 1500, 1st rate, x> 1500 2nd rate, and ask for price when x > 1500.</p>
<p>but their statement can imply: when x > 1500, you only use the 2nd rate. or, if you look at it another way, it can say that x <1500, and until it hits x > 1500, then changes. which means you would have to use the first rate until x = 1500, then switch to the 2nd.</p>
<p>it my opinion, it goes two ways. i said 11 + .062(x) or w/e that one was.</p>
<p>does anyone remember the problem in a little bit more detailed? my memory can be failing.</p>
<p>what was the graph question to this one?</p>
<p>i said the one that looked ilke a parabola but i think i’m wrong :(</p>
<p>im pretty sure it was A.</p>
<p>the 1/x shaped graph.</p>
<p>Iambored10, you are correct</p>
