Answer 1

21 years

Explanation:

M: distance she drives (miles)

G: no. of gallons used

125/6000 = 1/48

G = M/48

Or

M = 48G

M = 12000

12000 = 48G

G = 250 gallons

Each gallon: $2.4

Cost = 2.4 × 250 = $600

Evan's cost:

(12000/30) × 2.4 = $960 per year

Anna's fuel cost per year: $600

23740 + 960t = 31140 + 600t

360t = 7400

t = 20.556

Answer 2

Explanation:

Let C represent the Total Cost of the gasoline,

Let m represent the miles driven

C =

m (2.40) 48

Or

C = (0.05) m

Or other valid equation and definition of the variable

AND
