You buy hammers for $30.00 a dozen and sell them for 3.50 each. what is the percent markup for the hammers?

The percent markup is 40% cost: $2.50/hammer *40%=1.00 Cost+markup=3.50

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
