Lilit [14]

Answer:

If 30 unicorns out of 300 walk away then it will be 300-30=270 unicorns left.

If 50 dragons fly away out of 200 then it will be 200-50=150.

Therefore there are 270 unicorns and 150 dragons left.

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, wha

Otrada [13]

Answer:

$77.4

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 one gallon of gas $=\$2.58$

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

Hence cost of roundtrip to Springfield is $77.4
