Grade 10 Problem Solving Strategies CCSS: HSN-Q.A.1

Micah and two friends are taking a trip from Houston, TX to St Louis, IL, which is about 778 miles. The car they are driving gets about 26.4 miles per gallon and the cost of gas is about $2.50 per gallon. They will share the costs equally, what is the cost per person of the trip (assuming gas is the only cost). Use dimensional analysis to choose the expression below which correctly gives the cost per person of this trip.

$3 xx 778 xx 26.4 xx 2.5$
$1/3 xx 778 xx 26.4 xx 2.5$
$1/3 xx 778 xx 1/26.4 xx 2.5$
$1/3 xx 778 xx 1/26.4 xx 1/2.5$
