(disregard tax)

Let the price of a muffin be $M.  Then,

3M + 1.45 = 3.70

Subtract 1.45 from both sides

       3M = 2.25

Divide both sides by 3

        M = .75

So each muffin cost 75 cents.

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%2F3

==> x = 0.75

Thus, the cost of each muffin is $ 0.75

Hence, the solution.
