Answer:
The constant of proportionality is 12.
Step-by-step explanation:
Let's take a look at the formula give to us:
48=4k
First, we have to isolate the variable, K, by dividing 4 on both sides.
48/4=4/4 k
48/4=12
12=k
We can check the answer by plugging it back into the equation:
12*4=48
48=48
Hence, the variable k equals 12.
is this an algebra class? if so it just

Answer:
Each binder costs 30 cents or $0.30
Step-by-step explanation:
If Sarah's total was $9.05 and the binder costs 7.25 then in order to find the price of the folders you must subtract the cost of the binder (7.25) from the total (9.05) which leaves $1.80 as the amount she paid in total for 6 folders. Next, to find the amount spent per folder divide 1.80 by the number of folders which is 6 and your final answer should be 0.30.
9.25= 7.25+6x (next subtract 7.25 on both sides)
1.80=6x (next divide by six on both sides)
0.30=x
