1.25 1.25
12=r so she bought 12 roses
(to check if its right just plug in your answer 12 where your r is and you should get 15

Notice that 375º is the midpoint of this interval of temperatures. If we subtract all sides by 375º, then we get
so we can set 
and 
, and we can rewrite this inequality in terms of absolute values as
