a)$304
b)$312
c)$318
d)$328

Option B. $312

Step-by-step explanation:

Sabrina is planning a 1830 mile driving trip.

First we calculate the amount of gasoline would use in the trip.

∵ the mileage of her car = 24 miles/gallon

∴ for 1830 miles gasoline would be needed  =

                                                                          = 76.25 gallons

∵ the cost of 1 gallon gas = $4.09

∴ the cost of 76.25 gallons of gasoline = 76.25 × 4.09

                                                                = $311.86 ≈ $312

The approximate driving cost of the trip would be $312.

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
