Choose all that correctly compute the total cost, including the discount and tax. (round to the nearest hundredth)

25% off $39.25, and an 8% sales tax
total cost = $31.79
20% off $66.75, and an 8% sales tax
total cost = $57.67
40% off $45.90, and an 8.5% sales tax
total cost = $29.88
10% off $22.75, and a 7.5% sales tax
total cost = $20.10

a, b, c

Step-by-step explanation:

just took the test

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
