If you are given two points, do you know how to find the equation of that line?
This is the same type of problem
You are given (3, 2700) and (5, 3100)
Cost = mt + c , where t is the number of hours
(compare this to y = mx + b)
slope = (3100-2700)/(5-3) = 200
Cost = 200t + c
now plug in one of the points, pick the "easier" one (3,2700)
2700 = 200(3) + c
c = 2100
so <b>cost = 200t + 2100</b>
Now plug in t = 1.5
take over

The cost C Of making a dress is partly a constant and partly varies as the amount of time,T, it takes to make. If it cost GH¢27 when it takes 3 hours and GH¢31 when it takes 5 hours. Find the cost
