N = 5m
<span>n = m+35 </span>
<span>5m = m + 36 </span>
<span>4m = 36 </span>
<span>m = 9 </span>
<span>n = 45 </span>
dive the number of miles by the speed
so 450/60 = 7.5 hours
Let
X=<span>the original price of the pair of headphones
then
if the % </span>off sale is 40--------------- > (1-0.40)*X=<span>$36
