It takes 10 pounds of potatoes to make 15 pounds of mashed potatoes. At this rate: How many pounds of potatoes are needed to make 50 pounds of mashed potatoes?

33.333   or   33 33/100

Step-by-step explanation:

10 potatoes makes 15 pounds of mashed potatoes can be written like 10/15

and that means x potatoes make 50 pounds of mashed potatoes

so it looks like 10/15=x/15

so 10times20divided by15=x

x=

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.
