Makayla and David work at a furniture store. Makayla is paid $230 per week plus 7.5% of her total sales in dollars, xx, which can be represented by g(x)=230+0.075xg(x)=230+0.075x. David is paid $321 per week plus 4% of his total sales in dollars, xx, which can be represented by f(x)=321+0.04xf(x)=321+0.04x. Determine the value of xx, in dollars, that will make their weekly pay the same.
