Ryan is putting money into a savings account. he starts with
$450
in the savings account, and each week he adds
$30
let s represent the total amount of money in the savings account (in dollars), and let
w represent the number of weeks ryan has been adding money. write an equation
relating s to w. then use this equation to find the total amount of money in the savings account after 14 weeks.
equation=
total amount of money after 14 weeks= $?

the equation is S=30w+450

to find the answer just replace the w by 14

multiply 30 by 14 to get 420 and add 450 to it to get 870

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.
