IM Mathematics 3. A chef bought $17.01 worth of ribs and chicken. Ribs cost 1.89 per pound and chicken
costs 0.90 per pound. The equation 0.9c+1.89r = 17.01 represents the relationship
between the quantities in this situation.
Show that each of the following equations is equivalent to 0.9c+ 1.89r = 17.01.
Then, explain when it might be helpful to write the equation in these forms.
a. c= 18.9 -2.1r
b. r=-*c+9
