Jasmine is ordering 3 new uniforms for work online. The 3 uniforms cost $83.97. The company charges a flat fee of $15 for shipping and handling for each order. Write an equation that relates the total cost of the order and the number of uniforms. Is the relationship proportional? Explain. The unit rate is $.=$.fraction 83 dollars and 97 cents , over 3 end fraction . equals 27 dollars and 99 cents per uniform.

Let x = the number of uniforms.

Let y = the total cost.

=.+y equals , 27.99 , x plus 15

The relationship is not proportional. The shipping and handling fee does not depend on the number of uniforms ordered, so the cost is not a constant multiple of the number of uniforms.
