@satellite73 could you help me?

anonymous · Answer

replace $m$ by 320, compute $C(m)=0.6\times 320+40$

anonymous · Answer

$$C(320)=0.6\times 320+40=192+40=232$$

and this is the same? here?
Katie paid $18,802.80 for a Mustang. If the price paid includes an 8% sales tax, which of the following equations can be used to determine the price of the Mustang before tax?

(Let x represent the cost of the Mustang and y represent the total cost after tax.)

anonymous · Answer

$$18,802.80=x+.08x$$
$$18,802.80=(1.08)x$$
$$x=18.802.80\div (1.08)$$
