A cell phone plan cost $150 to start. Then there's a $30 charge each month. Is there a proportional relationship between the time in the cost of the cell phone plan? Type yes or no?

Yes

Step-by-step explanation:

Since in the question it is mentioned that the cost of the cell phone plan is $150 to start and after that it would be charge $30 for each and every month

So according to the every month, the charges would be applied

Therefore it is directly proportional to the time period

Hence, the answer is yes

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.
