Amacbook computer that sold for $900 last year now sells for 15% less. what is the new price?

$765

Step-by-step explanation:

The computer sells for 15% less meaning that it sells for 85% of the original price.  In math the word of means to multiply so we need to multiply $900 by 85% and to do that we'll need to convert 85% into a decimal which we can do by dividing my 100 and that gives us 0.85.  900 times 0.85=765.  So the new price is $765

I hope this helps and please don't hesitate to ask if there is anything still unclear!

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
