kasha drove 135 miles and used 5.4 gallons kf gas. if the fuel efficiency of her car remains constant and gas costs $2.59 per gallon., how much money can she expect to fill up her tank for an upcoming 300-mile road trip?

She can expect $31.08 money for her upcoming 300-mile road trip.

Step-by-step explanation:

Given:

Kasha drove 135 miles for 5.4 gallons of gas.

For 300 mile road trip, kasha needs 'X' gallons of gas.

To find X,

Rate = miles/gas

135/5.4 = 300/X

X = (300/135) / 5.4

X = 2.2*5.4 = 12 gallons

The cost per gallon = $2.59

The cost for 12 gallons = 12*2.59$ = $31.08
