Question 1071159
6. A bathtub which already had 25L in it is filling with warm water at the rate of 5L/minutes.
 A- construct a rule for the bathtubs volume, V (L), in terms of time, t (mins).
 My answer is V=25+5t
 B- how much water will be in the bathtub after 7 minutes?
 My answer is V=25+5(7), V=25+35, V=60
---------------
 C- if the bathtub can only hold 250L, how long will it take before it is dull?
------
V = 25 + 5t
250 = 25 + 5t
5t = 225
t = 45 minutes
=====================
A & B are correct
