Answer:
Mr X
Step-by-step explanation:
his identity is a variable ; it could be anybody of the male gender.
all the other ones denote known designations, i.e, B+ grade
To figure out how many miles the Daltons traveled the first day you times 2140 miles and 30 percent.
So 2140 x .30 = 642
They traveled 642 miles the first day.
To figure out how many miles they still have to travel you subtract your original miles (2140) from how many miles they have already traveled (642).
So 2140 - 642 = 1498
They have 1498 miles to still travel.
It is 5913.36. You have to multiply all of them together except that you have to turn the percent to a decimal before multiplying.
24: 10
12: 5 is equivalent to 24: 10
