Salma serra purchased a truck. last year she drove the truck 12,340 miles. the fixed costs totaled $1,428 , while variable cost totaled $2,998. how much did it cost per mile to operate the truck?

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076

thus, the first answer choice, y = sec x, is the correct one
