If Minimum Wage Kept Up With Inflation What Would A Big Mac Cost Today?

In 1980 the minimum wage was $3.35. A Big Mac cost $1.59. 

If wages kept up with inflation that Big Mac would cost around $7.00 today - but with a minimum wage of $17.00 (what 1980's MW would be in today's dollars) it would be much less of a bite out of a MW earner's hourly pay than it is today.
