Melodie, a super excited khan academy user, has increased her points by 75% in a week. she's at 14,000 points now. how many points did melodie have on khan academy last week?

8,000 points.

Step-by-step explanation:

Let x be the number of points Melodie have on Khan Academy last week.

We have been given that Melodie has increased her points by 75% in a week. She's at 14,000 points now.

We need to figure out x such that x plus 75% of x equals 14,000. We can represent this information in an equation as:

Upon dividing both sides of our equation by 1.75 we will get,

Therefore, Melodie have 8,000 points on Khan Academy last week.

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.
