Question 359508
If Matt baked cupcakes, all but 10 were unfrosted. He gave half of the frosted to his sister, half to a neighbor, and he ate half at dinner, then 6 were left. How many cupcakes did he have altogether?

Let x = # cupcakes in all.  Then x - 10 = frosted.
{{{(((x-10)/2)/2)/2 = 6}}},
{{{(x-10)/8 = 6}}},
{{{x-10 = 48}}},
{{{x = 58}}}.
