Answer:
Step-by-step explanation:
if t varies inversely proportional as r, then,
t ∞ 1/r
t = k.1/r
t = k/r
substitute t =6 and r = 5 into the equation above
6 = k/5
k = 5 x 6 = 30
the equation that represents this variation is given by,
t =30/r
tr = 30
when r =15,
t = 30/15
t =2

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
