Tam and gerri took turns driving during their vacation 2gether. they drove a total of 322miles gertmri dr...

Cont>> gerri drove 50 miles less than twice what. Tam drove. How many miles. Did gerri drove?

Let tam drive t miles and gerri drive g miles

So t + g = 322
and
t * 2 - 50 = g
or
t = (g + 50) / 2

Now
(g + 50) / 2 + g = 322

g + 50 + 2 * g = 2 * 322

3g = 644 - 50 = 594

g = 198 miles

Gerri drove 198 miles
Tam drove 124 miles
