Jeanias parents have given her an interest free loan of $100 to buy a new pair of running shoes .she plans to pay back the loan with monthly payments of $20 each. Instead suppose that Jeania borrowed $120 to get the newest model of running shoes and suppose that she pays back the loan with monthly payments of only $15 write a new rule for the balance of the function.

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.

ok thats very interesting

i would guess 26 because this isnt a sequential pattern or its to short to know
