Question 79359
Let "x" represent the number of muffins and "y" represent the number of number of juice bottles. 


That is according to the given data, he bought 3 muffins = 3x 


and one bottle of juice = 1y    and the cost of 1 bottle is $1.45 



The total cost of both of them were $3.70  


Thus, the linear equation is given by: 


3x + 1.45 = 3.70


==> 3x = 3.70 - 1.45 


==> 3x = 2.25


==> {{{x = 2.25/3}}} 


==> x = 0.75


Thus, the cost of each muffin is $ 0.75 


Hence, the solution.
