Question 1169085
h hotdog price
d drink price
 n nachos price

(nachos was $2.50 more than <b>three times the hotdog</b>.)
Going along the description literally you have {{{system(h+d+n=20.5,d=2h,cross(n=d+2.5),n=3h+2.5)}}};
If you are careful, this can be turned into a single equation in just one unknown variable.
