Solving exponential and logarithmic equations in exercise, solve for x.
e - 1.386x = 0.25

e - 1.386x = 0.25

Subtract e from both sides:

-1.386x = 0.25 - e

Subtract e from 0.25:

-1.386x = -2.46828182

Divide both sides by -1.386

X = -2.46828182 / -1.386

X = 1.780867 (Round the answer as needed)

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
