Step-by-step explanation:

GIVEN: On the trip from KC to Springfield, the church van consumed $15$ gallons of gas to go $179$ miles. If gas cost $\ 2.58$ per gallon.

TO FIND: Cost of a round trip to Springfield.

SOLUTION:

Distance of springfield from KC $=179\text{ miles}$

As it is a round trip total distance $=2\times179=358\text{ miles}$

As $15$ gallons gas used for $179$ miles distance

gas required for $1$ mile $=\frac{15}{179}$ gallons

gas required for $358$ miles $=\frac{15}{179}\times2=30$ gallons

cost  of $30$ gallons of gas $=30\times2.58=\ 77.4$

Hence cost of roundtrip to Springfield is $77.4
