1 gal. of primer and a brush. If the cost was \$30.44, find the cost of the brush.
I did rate*base=amount(r)the unknown (b) is \$30.44 (a)\$25.49 the total of the paint and primer. then I subtract \$25.49 from itself and \$30.44 and now Im stuck,, Help me please

• math -

Primer + paint = \$25.49

The total cost was \$30.44

The difference must be the cost of the brush.

30.44 - 25.49 = \$4.95 >> cost of brush.
